Visualisation Insights: #5 Head of Data Visualisation

This is the fifth article in my Visualisation Insights series. The purpose of this series is to provide readers with unique insights into the field of visualisation from the different perspectives of those in the roles of designer, practitioner, academic, blogger, journalist and all sorts of other visual thinkers. My aim is to bring together these interviews to create a greater understanding and appreciation of the challenges, approaches and solutions emerging from these people – the visualisation world’s cast and crew.

Alan Smith is Head of Data Visualisation at the Data Visualisation Centre for the UK Office for National Statistics (ONS). He is a visualisation expert with an extensive portfolio of innovative data visualisation solutions and is a well known champion of the importance of graphics in data analysis.

My reasons for approaching Alan about conducting a Visualisation Insights interview are quite straightforward. His position as head of this important unit gives him unique influence and opportunity to effect best practice visualisation techniques across the critical hub of data and statistical analysis provided by the ONS.

Just to be clear the views Alan expresses in this interview are his own and not necessarily those of the ONS.

Please can you give me some background about the Data Visualisation Centre? How long as it been established? What motivated its creation?

We started the Centre in summer 2007. ONS has a central Methodology Directorate – comprised mainly of small teams with expertise in the various elements of statistical production (designing surveys, analysis, estimation etc) and the one one thing that seemed to be missing was a dedicated team for getting information back in to people’s heads – what Hans Rosling calls ‘the final 6cm’. For some years prior to this, I had been running a GIS and mapping team in ONS’ Geography division, where I already had a cartographic visualisation remit. But it became pretty clear that the distinction between mapping and other forms of visualisation was becoming increasingly blurred, both in terms of tools and principles, so establishing the Centre was a great step forward.

What would you describe as being its principle remit?

On a broad level, I would say it’s to make sure that, as a producer of an enormous range of statistics, ONS takes the communication of its statistics seriously. What we’ve found over the last few years is that there are a lot of people producing statistics in ONS, and across the wider Government Statistics Service (GSS), who really care about their outputs, but lacked any formal support on how to implement things they were thinking about. Our unofficial motto is ‘making numbers meaningful’ and that is a principal goal – to allow users of our statistics to bridge the gap between data and meaningful information.

What is the make-up of the organisation?

We are a small team, currently just 4 of us. Our backgrounds vary, which is what I wanted from the outset – a multi-disciplinary skill set is much more flexible than 4 clones would be. So we have myself with a cartographic background, one colleague has a PhD in Visual Perception, one is a psychology graduate with a background in data collection and finally, we have a GIS/spatial analysis graduate.

Who are the key clients?

Key clients, inevitably, are internal to ONS, though we are keen to offer as much help as we can across the wider GSS. and beyond. ONS delivers a broad range of outputs right across the economic and social spectrums. With many of our web-based visualisation projects, we’ve been keen to share them across the public sector for reuse (with other data sets etc). There’s been some enthusiasm for that too, which has been tremendous. Looking forward, the forthcoming 2011 Census will deliver an avalanche of rich data which we are looking forward to working with.

How would you describe the profile of its work (advice, research, design work)?

It’s a mixture of everything really – which is what keeps it fresh, For a small team, we have a lot of hats to wear, so yes, there is an advisory/consultancy role, training, we develop and maintain standards on data presentation and also get involved with design and production work. This includes programming and more traditional DTP-style work.

What is your own background in Data Visualisation?

I can really trace this back to my time at the University of Colorado in the early 1990s, where I studied cartography – using ink and vellum. At the time, GIS was beginning to gather momentum and I remember being simultaneously excited and frightened by what was going to happen to the cartographic field going forward from there.

How long have you been aware of Data Visualisation as a subject field? What was your ‘eureka’ moment?

One of my major complaints about early attempts to produce any kind of maps on the Internet was how clunky, awkward and ugly they tended to be – essentially because software vendors were trying to replicate full blown GIS on the web. I began to miss the control over design you get with pen and paper. While I was fishing around for a dissertation topic for my MSc (in GIS), it became clear that the solution was not going to come from the traditional GIS community, because, at the time, they just didn’t ‘get it’. I began searching further afield and ended up finding many more kindred spirits in the visualisation community rather than in straight-laced GIS.

Who would you describe as being the most influential (to you) practitioners/authors around visualisation?

There have been plenty. For me, Andreas Neumann was the first to demonstrate that you could deliver elegant, interactive data visualisations, combining maps, graphs and other visual forms, using nothing more than a web browser and open standards. His early work – such as the social patterns and structure of Vienna map – was tremendously influential. In the cartographic field, Jason Dykes, Mark Harrower and Danny Dorling spring to mind as people whose work make me sit up and think. I also admire Hans Rosling who has been very keen to push visualisation to support decision-making and public policy. I am always inclined to support the people who think of visualisation in these terms rather than as a pure ‘beautification’ exercise.

There’s a new wave of statistically literate journalists who are producing some great work – for example, Mark Easton, Ben Goldacre, Michael Blastland and Simon Rogers. If we can help people like them get to the information in our data quicker, then that’s a key objective of ours met. In my own team, Dr Steven Rogers, who has a phenomenal understanding of perceptual systems, is a continuing source of entertaining discussions and new ways of looking at familiar things.

More recently, I’ve also spent more time looking backwards than forwards. So people like William Playfair, who invented modern data graphics as we know them, Charles Booth, Willard Brinton, Jacques Bertin. It’s tremendous to look at what they did and think what they would make of where we are now (probably, simultaneous horror and excitement).

What learning resources (eg. websites, blogs, journals, books etc.) do you most commonly refer to or immerse yourself in?

There are plenty. Edward Tufte’s books are probably the ones you would keep on your coffee table if you had normal folk coming round for a coffee. Stephen Few’s books are the safety-first manuals we keep around next to the First Aid kit. A little known magazine outside of the statistical world is ‘ Significance’, now published jointly between the Royal Statistical Society and the American Statistical Association, has some lovely articles which I would seriously encourage people to read. I’m always coming across interesting web content, which I try to bookmark on my account. The New York Times website is great, there’s some tremendous stuff there. For people involved in communicating about statistics, there’s the BlogAboutStats. My favourite visualisation blogs are information aesthetics – and yours of course 😉

Are there any software developments that particularly excite you?

I am particularly excited by the second-coming of SVG (Scalable Vector Graphics), which is now embedded in the nascent HTML5 specification. It is becoming exactly what I first hoped it would be – HTML for pictures. With proper support across most browsers, we should see some really exciting things coming from that area now.

In terms of software, web-based tools like MapShaper and IndieMapper are very exciting. Also, the profound influence that something like Google Maps has made on the public subconscious. Although there are many concerns over the degradation of traditional geography skills, you can’t argue that things like GoogleMaps and Location-Based Services in general haven’t made geographic information meaningful to people.

Regardless of the fight between Adobe and Apple, I am still a big admirer of both companies. They make great hardware and software that makes our jobs (usually) easier and more enjoyable.

Are there any particular trends in the field that particularly excite you?

The move to open standards for web visualisation.  Even Microsoft are now on board. A web browser has now got to be the most ubiquitous piece of software in the world and they now all have built-in support for sophisticated visualisation techniques like animation and interactivity. It’s a real pity when web content fails to take real advantage of this. Free libraries like Processing.js should encourage some real innovation in visualisation too.

More broadly, the fact that people now expect the web to be engaging means there are real opportunities for bringing information to people who previously wouldn’t have have gone near official statistics. Visualisation gives us a chance to let people see official data in a more personal, meaningful way. They can visualise their own inflation patterns based on their own spending habits, compare their neighbourhoods and cities with others, see how long they are expected to live, all over a cup of coffee, using just a web browser. That’s an exciting thought and I think we are only just scratching the surface. The real power of all this convergence is going to be what happens when we bring different data sources together – as long as its done skillfully, rather than just for the sake of it.

Are there any matters that particularly disappoint or frustrate you?

Yes – but a lot of the things that generate frustration also mean we are never short of work! I get frustrated by all of these things at various times, but have to recognise we have had minor and major victories in those areas too.

What is your perception of the era of open data and transparent access – do you feel this is a positive move or is it somewhat superficial given we are essentially making data available to non-experts (in both analysis and domain knowledge)?

Overall, I think it’s a very positive step, though it’s not without issues and challenges. If I ever needed to demonstrate that numbers alone, without context, do not equal meaningful information, then the enormous amount of content dumped onto things like is almost a self-authored case study. Just making data available, by itself, solves nothing.

However, I find the issue of non-expertise interesting and potentially patronising. Traditional notions of statistical literacy, based on numeracy, are ripe for challenging, I think. For example, here in the UK, Camelot had to withdraw a lottery scratchcard a couple of years ago (‘cool cash’) because it required people to compare negative numbers and too many people found that difficult. Poor numeracy was acting as a barrier to problem-solving. However, it would have been perfectly feasible to present the same information in a different way (for example, to ask them to identify a warmer or colder temperature, rather than a higher or lower number) and many of the same people would have been able to solve the problem. We are sometimes lazy in that we are happy to let an issue like poor numeracy act as a barrier when there are ways around it. I’m not saying we should ignore numeracy issues – but improving numeracy is something with a very, very large turning circle. 15 million adults in the UK lack Level 1 numeracy skills – but these are people – intelligent people – who need to handle data now, so there’s a challenge up front for people working within the data/information visualisation.

What role can the Data Visualisation Centre play in safeguarding the positives of this shift in attitude towards data access?

On a simple level, we’d like to see ourselves as just one place where people can come to for ideas on how to visualise data, recognising that there are many others too. I am particularly keen that we play a role in what at ONS we call ‘Wider Public Reporting’, which involves how we engage with people beyond traditional statistics users. There is definitely a need to unlock the expertise and insight that is acquired during the process of making official data. One option for this is syndication of one sort or another. I recognise that not many people are going to browse ‘‘ over a sandwich at lunch (2 of their least favourite words in a URL!) – but they might look at the same content if it was hosted on the BBC, The Guardian, or The 10 O’clock News for example. The Met Office is a good example, I think, of a recognised authoritative source of official data, which is served to many different channels in many different forms for a variety of audiences.

Could you provide a brief outline of how a typical visualisation project may come about and evolve?

Normally, a spark – and buy-in – from the parts of ONS that produce the data is the starting point. How things proceed from there depends on what that spark is. I remember presenting the first animated population pyramid as a fait accompli to our demography area, mainly because we were playing with their data and wanted something less complex than a map to test out our ideas. But most projects end up being a collaboration based on their knowledge of their data and how it is used together with out understanding of how we can exploit it.

Which visualisation tools do you mainly use in the DVC? Are there any that you don’t currently use that you would like to?

Our general approach has always been to figure out what we wanted to achieve and then work out a way of implementing it – so we never let the tool determine the way forward. Having said that, we very often end up with the usual suspects – Adobe Illustrator, Photoshop, Flash, various open web technologies (HTML/SVG/CSS) because they are so flexible and between them cover most of our requirements. Excel is never far away either, as most data at one stage or other seems to pass through it. We tend to avoid tools that have proven difficult to deploy across the web, sometimes restricted by our own infrastructure or the ability of users to access it.

How would you describe your progress so far in promoting and succeeding in the better practice of visualisation/design?

It is a never ending job. But more people across official statistics now take notice, so there’s a partial success.

Do you have a particular design style/standard that you use for reference in handling visualisation project work?

Yes – to try and make the designs unobtrusive and place the visual emphasis firmly on data and information. We are gradually evolving a house style that reflects that. As with all things, we don’t want the design style to be a straight jacket, but a little consistency is a good thing for the end user.

How do you handle the issue of aesthetic design with functional performance of a visualisation?

Carefully. It is not a crime to make a data graphic look attractive and engaging – but if it is over-egged, it can actually be counter-productive to your overall goal. So we tend not to go for gratuitous visual effects (drop shadows, 3-d treatments, shimmering reflections) as these can lead you down a slippery slope. We’re also very careful in our use of colour – both from a web accessibility perspective and from an aesthetic angle. Another thing we have to be careful of in the statistical arena is natural colour associations with certain topics. Often, the simplest symbology is the best. For example, it is easier for the eye to estimate quantity from length than area, – so lines, not blobs, are often more effective if you want people to interpret quantity correctly.

How do you articulate the true benefits of data visualisation?

When people use visualisation as a route into data that would otherwise pass them by – so, catching a wider audience, or revealing insight that would otherwise be hidden. These are things that data visualisation brings – to experts and non-experts alike. Playfair said that ‘…no study is less alluring or more dry and tedious than statistics…unless the mind and imagination are set to work‘ – that’s the role of data visualisation. The information in the data is beautiful, not the graphic itself.

Do you ever come under particular pressure from clients/customers claiming to know what they want in terms of presentation of information? How do you handle this?

Yes – and many of them are right! The “ageing map of the UK” we produced was a reflection of a very well developed sketch from Shayla Goldring in our demography team, who had a clear idea of what she wanted to achieve. Having said that, there have also been occasions where we have had to step in and advise our clients of best practice and, if necessary, enforce it. But it is very rare for things to turn into a stand-off.

Would you be able to identify an example of a particularly effective visualisation project you have worked on?

In terms of sheer market penetration, the animated population pyramids, which have proliferated into many different variants, have been a favourite – and a good example of starting out with something basic and rapidly iterating it based on customer feedback. We have also had plenty of people from around the world reuse these templates with their own data, which has been very gratifying. On a personal level, satisfying my cartographic DNA, the flow-mapping in our CommuterView product was a lovely project to work on, I want to revisit that one in the near future with a modern toolkit.

Have you any examples of particularly creative or innovative approaches beyond the standard graphical approaches (eg. bar/line graphs) that you have recommended?

Boxplots. We’re big fans of boxplots for multiple distributions. They were devised by John Tukey, the father of Exploratory Data Analysis, who championed the used of graphics for spotting things you’re not expecting to see.  There have been alot of recent innovations – technology’s been great for encouraging it – but my view is that there’s alot of mileage in applying new techniques to the standard displays – the best of both worlds!

How do you assess the success of your visualisation services?

Repeat demand! We do monitor feedback, both good and bad, and hope it will help us make better products in the future.

Finally, how would you like to see the Data Visualisation Centre evolve/progress over the next 3-5 years?

In the current climate, survival is success! Beyond that, I’d like to feel that success is making the Centre recognised as an integral part of ONS’ workflow, delivering core outputs, not just an ‘added value’ thing. If it can help draw attention to the wealth of information in ONS data, then so much the better.

I’m extremely grateful to Alan for his wonderfully candid and detailed responses to the many questions I posed him! He has perfectly encapsulated the purpose of these insights articles providing some rich perspectives from his unique role in this field. I wish him and his colleagues at the Data Visualisation Centre all the very best for the future. You can keep a track on Alan’s bookmarked discoveries via his graphboy del.ici.ous account.

Mapping America: More visualisation brilliance from NYT

Its been a great start to the week in the world of visualisation with Paul Butler’s terrific design showing some fascinating patterns of Facebook friends and Nathan Yau reminding us of some of the best work that has taken place this year. Now, the New York Times graphics team have joined the party with the stunning project ‘Mapping America‘.

Inspired by the excellent Chicago Boundaries project by Bill Rankin, Matthew Bloch and Shan Carter have created an interactive mapping interface which layers a range of demographic information for every block in every city of America. This creates an amazingly detailed and revealing picture of the diversity of America’s population.

You can choose to display a range of different layers of information relating to race and ethnic distribution, income patterns, housing and domestic matters as well as education subjects.

The brilliance of this work is particularly demonstrated by the dexterity of its interactivity which allows you to smoothly navigate across the country, search for zip codes, zoom in and out to enhance the levels of detail. Helpfully, hovering over individual blocks brings up a dialogue box with specific data for that area.

Congratulations to all involved in this work, it really is exceptional.

‘Visualisations in the wild’ contest: The winner!

On Friday I announced the two finalists battling it out in my ‘visualisations in the wild’ contest. Over the weekend and right up to an hour ago I’ve been inundated with email messages, tweets and post comments from readers casting their vote for which visualisation they believe best captures the essence of this competition.

The contest is now closed and I’m delighted to announce that Visualisation B, the Duracell Powercheck, has been declared the winner with 75.2% of the votes.

Congratulations to Jan Willem Tulp who wins a Full Conference Pass to the O’Reilly Strata ‘Making Data Work’ conference taking place in Santa Clara, CA in February 2011.

Commiserations go to Naomi B Robbins who was a very respectable runner-up and received a lot of support for her excellent submission but ultimately just not enough to beat Jan.

Many thanks to all who voted and also, once again, to those who entered the competition.

‘Visualisations in the wild’ contest final: vote for your winner!

A couple of weeks ago I launched a contest for one lucky reader to win a full conference pass to the O’Reilly Strata ‘Making Data Work’ conference taking place in Santa Clara, CA in February 2011.

The theme of this contest was visualisations in the wild and the challenge was to submit a photo of a great example of best practice information design being used in everyday life. I was looking for unique examples that demonstrated the value and power of good visualisation practice, designs that help to make everyday life go by that little bit more smoothly.


The contest has now closed and I have narrowed it down to two entrants who now go forward as the finalists. One of these was submitted very early in the contest and was the clear leader until late yesterday evening when I received the other submission.

Originally I was going to judge the winner myself but I think it will be more fun and more democratic to open this process up. I would therefore like to invite Visualising Data readers, subscribers, followers and casual visitors to submit their choice for which is the best visualisation in the wild example (see below for instructions).

Visualisation A

(Click on image above for larger view or click here for the original AFSC design in pdf)

Entrant’s Description: 3ft Quaker appeal to spend on peace – not war. Shows % discretionary budget on military (red) and other categories. Powerful help to visualize and understand big numbers. The data is also available on in a pie chart, but I find the long strip to be much more powerful.

Visualisation B

(Click on image for larger view or click here for original demo of Duracell Powercheck)

Entrant’s Description: Duracell’s interactive animated single bar chart shows remaining battery charge in yellow when holding the battery on the dots.

Voting Instructions

Your assessment for choosing your preferred visualisation should be based on two criteria:

  1. How well the visualisation functions – the accuracy and clarity of the information exchange
  2. How elegant the visual design is – its visceral appeal

The only other rules are that the entrants themselves cannot submit a score and I also won’t accept any input from Sepp Blatter or anyone else at FIFA.

To submit your preference simply let me know which visualisation entry above (A or B) gets your vote either by commenting on this blog post below, sending me a tweet or sending me an email.

The closing date/time for all votes is 12:00 UK time on Monday 6th December. I’ll announce the winner shortly after.

Good luck to the finalists and thanks for all the entries!

Tableau removes WikiLeaks visualisation

Fascinated to read in the mainstream press about Tableau’s decision to remove a series of visualisations published by WikiLeaks using Tableau Public, following pressure from Senator Joe Lieberman. Elissa Fink of Tableau has published an explanation of the background behind this decision.

The key excerpts from this explanation are:

Our terms of service require that people using Tableau Public do not upload, post, email, transmit or otherwise make available any content that they do not have the right to make available. Furthermore, if we receive a complaint about a particular set of data, we retain the right to investigate the situation and remove any offending data, if necessary.

Our decision to remove the data from our servers came in response to a public request by Senator Joe Lieberman, who chairs the Senate Homeland Security Committee, when he called for organisations hosting WikiLeaks to terminate their relationship with the website.

This is clearly a very difficult matter which has caused a great deal of reaction in support of and in opposition to Tableau’s decision as you will read in the comments section.

My view is it is very unfortunate that Tableau has had come to this decision. I don’t necessarily think they believe their ‘terms of service’ reason, especially given this data is now so widely cascaded on the Internet. Unfortunately, it does create a tricky precedent that will be interesting to keep an eye on over time with Tableau users likely to test the boundaries of this policy approach on other subject matters and data contexts.

I generally support what WikiLeaks stand for (though I find the cablegate release less about whistle-blowing and more about diplomatic gossiping) but you cannot ignore or be complacent about the massive baggage that comes with any slightest association with the organisation. The reactions this organisation stirs around the world is quite incredible. I have had limited but first hand experience of dealing with the same potential difficulties of association.

Do we actually expect a private company like Tableau to be waving the flags on the frontline of free speech activism? Lets be realistic, no. But I’m sure their organisational values are generally sound so lets not go over the top on the possible shortcomings of principles they hold dear and instead take a look at the bigger picture.

The action Tableau has taken is regrettable but it has been done so in the context of pressure being mounted by the American government and Joe Lieberman, in particular, on organisations associated with WikiLeaks, no matter how tenuously. You have to say though, had the pressure yet got that heated or could they have held firm a bit longer? Unfortunately for them, and probably us too, Tableau are likely to be bloodied and bruised by taking this decision.

BBC going deeper into visualisation

A couple of items of news have popped up this week which give further evidence of the growing mainstream appreciation and appeal of visualisation. The fact both involve the BBC is very encouraging and continues their recent coverage of this subject following their Newsnight programme featuring David McCandless back in August.

The Joy of Stats

The first item regards the announcement of a programme titled ‘The Joy of Stats‘ which is going out next Tuesday 7th at 21:00 on BBC Four:

A documentary which takes viewers on a rollercoaster ride through the wonderful world of statistics to explore the remarkable power they have to change our understanding of the world, presented by superstar boffin Professor Hans Rosling, whose eye-opening, mind-expanding and funny online lectures have made him an international internet legend.

As many have already remarked, we in the UK are very fortunate to be able to see this though no doubt it will be made accessible in some way, shape or form to non-UK followers in due course. I’m sure it will prove to be a great show if the preview clip below is anything to go by.

A couple of grumbles though. Firstly, I always struggle to get my visuals around (if indeed visuals can get around) log scales so I’m a bit concerned that your average punter watching this might be a bit misguided as to how values are progressing along the x-axis. It could also be slightly misleading to the untrained eye that the y-axis does not begin at zero.

Secondly, why can’t descriptions of programmes like this avoid using lazy phrases like “superstar boffin” and observations like “Rosling is a man who revels in the glorious nerdiness of statistics“. This is such patronising rubbish, it really winds me up. Why is it nerdy to be passionate about something? Especially when it is around a subject as important as global health and poverty. Its not like these are particularly advanced examples of statistics anyway. Rant over.

BBC Backstage DataArt

The next item to grab my attention was discovering the BBC’s Data Art project which is an interesting sub-site focused on developing and showcasing examples of innovative visualisations relating to BBC data. The project is a collaboration between BBC Learning Innovation and the Centre for Research in Education, Art and Media (CREAM) at the University of Westminster.

The site contains a range of useful resources, guides and data sources as well as full details behind the development of all the visualisation projects. One example project currently being profiled allows you to compare mentions of certain terms in the news coverage on BBC Americas. For example comparing terms such as Obama vs. Bush produces the display shown below and navigating around this interface leads you to explore the database of specific news items.

Visualising Data – 100 not out…

It almost passed me by unnoticed but I realised I made my 100th blog post yesterday and so I felt justified to compile a self-indulgent post to celebrate the fact.

For those of you from non-cricket playing nations, 100 not out is terminology used to describe a player who has reached the treasured milestone of 100 runs, a feat traditionally marked by the player acknowledging all those in the ground, as above. With only a day to go before the first Ashes test in Australia, it seemed an appropriate visual.

Main reflections

It has taken me quite a while to reach the hundredth post, I originally expected to be hitting this mark about 5/6 months from launch but maintaining a degree of editorial consistency removes the temptation to simply regurgitate material from elsewhere or churn out off-topic content for the sake of pursuing greater volume. Still, a 1 post per 3 day ratio isn’t bad and I’m fairly satisfied with the range and depth of articles I’ve worked on during this initial period of existence. I’m delighted with the growth in readership on the site which has been consistent from day one. I’m aware that there now exists an increasingly cluttered blogosphere around this subject so I’m constantly working on plans to try and find a niche market position.

Future plans

Aside from a further set of great articles for the Insights series, the most pressing priority, posts-wise, is a series I’m running before Christmas that will present an extremely comprehensive collection of tools, resources, knowledge etc. relating to the field of visualisation. It will be themed around a seven-day release, each day covering a different range of important resources. These will subsequently have a permanent presence on my (currently sub-standard) resources page but will be constantly evolving to reflect the emergence of new, contemporary references and reader recommendations.

I said a few months ago that I wanted to find time to do more design work for the site, utilising the fantastic tools and data sources that now exist to help practice what I preach. Alas, time has not been found, so I need to redouble my efforts to follow this up. I am also buckling under the weight of pressure from knowing that I’ve not yet written up my research paper. This must be done by February!

I am also hoping to launch a Data Visualisation training programme here in the UK early in 2011. More on this in the new year, however, if it is something that interests you please get in touch and I’ll be able to collate a better sense of where in the country I might wish to arrange such sessions.

Visualisation Contest

Another reminder about the visualisation contest I am running for one lucky reader to win a Full Conference Pass, worth up to $1500, to the O’Reilly Strata ‘Making Data Work’ conference. The theme of this contest is visualisations in the wild and the challenge is to take a photo of a great example of best practice information design being used in everyday life.

Finally, a big thank you…

Aside from my family, my agent and my publicist, I would like to extend a massive thank you to everyone who has visited the site, commented on articles, shared articles, emailed me, subscribed to the site, bookmarked the site, ‘liked’ me on Facebook and followed me on Twitter. Here’s to the next 100 posts…

Reflections from BBSRC/AHRC Visualisation Conference

I spent a couple of days last week in Bristol at the Biotechnology and Biological Sciences Research Council (BBSRC)/Arts and Humanities Research Council (AHRC) Workshop on “The Challenges of Visualising Biological Data“. It was a great privilege to have had my expression of interest converted into an invitation to this (possibly) one-off event and I wanted to capture some headline reflections.


The BBSRC and AHRC are two of the seven major bodies that make up Research Councils UK, funded by the Government but existing as Non-Departmental Public Bodies. Research Council funding is only awarded to the very highest quality research and so, by extension, they are very influential and powerful bodies. For them to recognise the growing emergence and importance to research of visualisation is a very positive and welcome development, signalling a commitment to promote and exploit contemporary visualisation methods for analysing and communicating research activity.

The objectives of the event were outlined as follows:

The intended output of this event will be a public available report articulating the thoughts, discussions, ideas and recommendations to emerge from the two-day event. However, the collaborative connections and relationships that may emerge from the event will also be a definite positive outcome.

Key Observations

The Buzz – I have spoken recently about my promotion of the Strata conference and one of the key aspects of this backing was my liking of the potential make up of delegates coming from a spectrum of disciplines and organisational domains. The same applied to this event with scientists, creative researchers, computer scientists, academics from the humanities fields and information scientists brought together under one roof.

A varied delegate mix is absolutely essential to ensure a conference has legs (during and after), encouraging people to step out of their domain expertise, meet with others, socialise, exchange thoughts and ideas. This unique type of energy (a curious journey through mutual suspicion, territory-crossing caution, timid connection, cross-fertilisation and finally inspiration) is almost impossible to achieve to the same extent when you only have a single group represented, which can happen with many conference occasions. The poster and demo sessions, in particular, were very loud, busy and lively affairs with energetic discussions taking place throughout the event.

Presenters – It is impossible to expect a gathering of presenters and subjects to all make a connection with all delegates and so it is not intended as any kind of criticism when I say I only really derived value from about 50% of the presented material. Typically, this was when the presentations touched on issues of theory around visualisation.

In particular, I was really delighted with the talk given by Prof. Sara Fabrikant, Head of Geographic Information Visualization & Analysis Unit at the University of Zurich, which contained many research themes relating to how users interact with visualisation on both aesthetic and performance levels. Special mention also to the opening presentation from Prof. Katy Börner, Professor of Information Science at Indiana University (amongst several other roles).

I was slightly surprised not to see the Arts and Humanities side of the event represented by a speaker. I understand it was largely a BBSRC led event but it would have been refreshing to see a non-science focused presentation at some stage.

I felt there were several occasions when an example of visualisation was exhibited in a positive light, when in actual fact they demonstrated several characteristics of flawed design. One in particular stuck in my mind: a tree diagram with the final nodes represented by pie charts of varying radius which failed on quite a few levels. On the plus side, I was impressed that there was consistent recognition of the different roles visualisation plays in exploring/analysing data vs. communicating information.

The Group Sessions – For me the highlight was the achievement of the two group discussion sessions where about 8 random (or not so random!) people were thrown together and asked to work as a collective discussing a handful of visualisation-related problems, issues and responses to statements. Rather than being paralysed by the clear perceptual differences that existed, these sessions seemed to flourish with the ingredients each person brought creating a great recipe to feedback to the rest of the conference.

The first session explored issues around complex data, how visualisation can aid the analysis and communication of it, and the second focused more on what makes a useful visualisation tool, what would be its key features etc.

The only shame is that we didn’t have chance to spend longer focusing on the key skills required in visualisation because I feel these are possibly more pressing than identifying specific characteristics of desired visualisation tools. We need to equip our scientists and researchers (both established and upcoming) with the visual thinking capabilities and broad design knowledge that helps them understand the key principles of visualisation, how the brain most efficiently processes information, why a multiple series of pie charts is not an effective method of displaying data etc. As Stephen Few remarks, these skills are not intuitive and must be learned.

There exists a pyramid of capability requirements: the ‘masses’ requiring visualisation basics, a smaller population require these taking to a more advanced level and then you move towards a smaller, upper group seeking the capabilities to author or knowledgeably commission their own visualisation tools and solutions.

I would love to see, as one of the recommendations from this session, a focus on developing a learning & teaching provision across all levels and domains of academia that equips people with the methods and inspiration to pursue better visualisation practice. Hopefully, this increased knowledge would permeate beyond visualisation alone and encourage an improvement in the design of presentation slides, which I have to say seemed to tend towards the rather bleak bullet-pointed deck at this event.

Overall, a very good event, well run by the BBSRC/AHRC, I was delighted to have been there and I keenly await the final report and the potential of future opportunities in this field.

Visualisation Contest: Send a great example from ‘the wild’

You may have seen a recent post where I published details of a great event being held in February 2011. The O’Reilly Strata ‘Making Data Work’ conference will bring together a unique blend of professionals, experts and innovators from all walks of the data world, including a very strong visualisation presence.

For those who can make it, once again, allow me to express my recommendation that you attend. To register your interest, click here, and don’t forget to use the 15% event discount code for Visualising Data readers: str11vsd.

However, if you can a short while, you may be able to attend the event entirely free of charge. I’m delighted to reveal details of a competition I am running to give one lucky person the chance to win a Full Conference Pass to the event, worth up to $1500.

The Contest

The theme of this contest is visualisations in the wild and the challenge is to take a photo of a great example of best practice information design being used in everyday life.

I’m looking for unique examples that demonstrate the value and power of good visualisation practice, designs that help to make your day go by that little bit more smoothly. It might be the display on your clock radio, the dashboard in your car, the arrivals board at an airport, maybe some food information on packaging or even the instruction diagrams to build a cupboard. It might be something so small, so minor, so mundane but equally so elegantly efficient at communicating some information.

How to Enter

To enter all you have to do is send me a photo or video of your example and accompany it with a short explanation of why you think it is a great representation.

Please keep the description brief, ideally using a maximum of 140 characters to keep it Twitter-proof.

Send your submissions to me on email or via a direct message on Twitter @visualisingdata.

How Will the Winner be Judged?

The assessment will be based on two criteria:

  1. How well the visualisation functions – the accuracy and clarity of the information exchange
  2. How elegant the visual design is – its visceral appeal

The only rules are that I won’t accept examples from print or digital media nor from corporate/commercial setting. For example,  don’t send me photos of a graphic from the New York Times, screen shots of a TV graphic, nor your company’s latest monthly sales report. As I’ve said above, it is about sharing examples of the everyday information designs – visualisations from the wild – that interest me. I will let you know if you’ve innocently violated these rules to give you chance to re-enter!


The contest is open now and will close at midnight on Friday 3rd December. I will reveal the winner on Monday 6th December.

Good luck and happy visualisation hunting!
