Confirmed training dates for 2014

I now have the final confirmed locations and dates for my data visualisation workshop schedule for the initial part of 2014. Chicago (16th May) and Montreal (19th) were the final outstanding pieces in the jigsaw.

Visit the training page to find more details for each event or to commence your registration.


Note that for non-Europe based courses there are some 10% discount earlybird tickets available. Specific venues for each event are being organised as soon as possible, but they will always aim to be in convenient locations, central to each city being visited.

10 significant visualisation developments: July to December 2013

To mark each mid-year and end-of-year milestone I take a reflective glance over the previous 6-month period in the data visualisation field and compile a collection of some of the most significant developments. These are the main projects, events, new sites, trends, personalities and general observations that have struck me as being important to help further the development of this field or are things I simply liked a great deal. Here’s the full compilation of all my collections.

At the end of July I published a collection for the initial 6 months of 2013 and now I’d like to mark the closing of 2013 with my latest perspective. I look forward to hearing from you with suggestions for the developments you believe have been most significant.

And so, as ever, in no particular order…

1. HelpMeViz


HelpMeViz is a really great idea from Jon Schwabish, motivated by the lack of a suitable platform outside of Twitter to offer the community a means of satisfactorily commenting and providing in-depth critique on data visualisation projects. The site is open to anyone who is seeking feedback on their visualisation designs to submit their work and commence a conversation. It is designed to be very inclusive and especially constructive, welcoming to all levels of designer and for any type of visualisation work. Over time, I would anticipate there will be plenty of functional enhancements incorporated in to the site but, for now, I urge anybody seeking advice/evaluation for their work to give it a go. Likewise, any folks in the field who are able to offer such advice, please do contribute.

2. Earth Wind Map


So new on the scene is this project that the D3 paint over Africa is not even dry. This is the beautiful Earth Wind Map, created by Cameron Beccario, and inspired by the Wind Map project of 2012 (great to see the attribution). It is entrancing to the point of hypnotic.

3. News-Graphics Job Changes


This rather stretched revolving-door metaphor is intended to visually summarise the flurry of changes amongst newspaper graphics editors and interactive designers witnessed over the past few months (and 2013 in general). We have seen numerous arrivals, departures, promotions and movements between some of the top newspapers, particularly in the US, as the graphics teams shuffle their packs. Names such as Gregor Aisch, Kennedy Elliott, Jennifer Daniel, Alan McLean, Wilson Andrews, Javier Zarracina, Alvin Chang, Derek Watkins, Simon Rogers, Alastair Dant, John Burn-Murdoch, Simon Scarr and Richard Johnson are just some of those I can recall moving roles during this period.

4. Subtleties of Colour


A really excellent 6.5-part series of in-depth articles about the use of colour to display data from the pen (or keyboard tapping fingers) of NASA’s Rob Simmon. It is a brilliantly comprehensive, well-structured and – importantly – accessible discussion on the fine balance between right and wrong in this critical aspect of visualisation design.

5. Age of Buildings


One of the most prevalent project topics over this last period has involved the creation of absorbing, interactive displays to explore the patterns of the ages of a city. These projects use different portrayal methods (colour, shade, 3D spikes) to capture the tapestry of the age of the buildings across various cities. A selection of the most prominent projects I have seen were for Portland (OR), Chicago, Brooklyn and Amsterdam.

6. WTFViz


What the Flip…? WTFViz does what it says on its Tumblr-shaped tin: a celebration of visualisations that cause severe head scratching and confused wonderment. It is the trash compactor of the visualisation field. Rather than Han Solo and gang wading amongst the detritus we can thank Drew Skau for rolling up his jeans and getting in amongst the stink. For a more positive celebration collection check out the prettier counterpart site ThumbsUpViz and the more noble collection of trash that is Accidental aRt.

7. Living United States Presidents


A very personal choice for this entry but I just really liked the insights from and the execution of this project that explores the concurrency of living presidents past and present. We are seeing more and more floating bar/Gantt chart works, for which I raise both thumbs, and this approach works so well for this project. The interactivity is superbly judged too, just utilising the hover event across the line chart’s timeline. The final result is a great demonstration of the discipline in reduction and simplicity, without treading into the murky waters of minimalism.

8. Mars Curiosity Rover


This project from Jonathan Corum and Jeremy White of the New York Times tracks the Mars Curiosity Rover on its daily journey exploring Mars. It provides a route map of its day-by-day position and distances travelled, an annotated timeline of each day’s adventures as well as presenting key images collected by NASA. Regardless of whether you are a space science enthusiast this is just such a brilliantly accessible and endlessly fascinating way to tell the story of little Rover’s expedition.

9. IXT/NZZ Swiss Maps


Another mapping-related entry in this list concerns the fabulous series of work produced by Interactive Things for Swiss German-language Newspaper Neue Zürcher Zeitung. Working with the editorial team at NZZ, the 4-week project aimed to reveal new connections and developments within Switzerland through cartographic representations. Here’s the original and translated collections.

10. RAW


Hopefully evidence of more offerings like this. RAW is a tool developed by Density Design lab that undertakes a middle-man role, sitting on top of the D3.js library but providing an interface to create custom vector-based visualisations. Inevitably you lose some of the design control but that is a worthy sacrifice if it helps take away the pain – and potential obstacles for many – of hardcoding from scratch.

Special mentions…

Here are the other highlights from the latter half of 2013 that deserve a proud nod from their creators having just missed out on the prestigious main list by the width of a dart (disclaimer, darts are not used for these selections. The magic 8 ball does a good enough job):

Black Budget – Really strong project from the Washington Post to explore the US ‘Black Budget’, spanning dozen agencies that make up the National Intelligence Programme.

Sci-Fi Spaceships – Incredibly detailed, painstakingly crafted and beautifully composed illustration to create a single graphic that visually compares the size of some of the most notable starships from science fiction

Bechdel Test – Outstanding exploratory visual analysis of the Bechdel test in movies.

Finding the Quiet City – Lovely project from the New York Times to crowd-source the quiet parts of New York’s boroughs, mapping their location and descriptions, and occasionally including short audio and video excerpts.

Jobs Board – Already mentioned on my previous 6-monthly collection but Lynn Cherny’s data-vis-jobs Google Group goes from strengh-to-strength with an increasing frequency of new opportunities. Check it out and contribute!

In praise of slopegraphs

I love slopegraphs. I’m happy to nail my colours to the mast and declare it. I’d probably not go as far as to wear a t-shirt with such a slogan but I feel a need to express my praise for the still-underused slopegraph and try help continue spread the word of its worth.

The typical application for using a slopegraph is for a before and after story. Its key value is that it provides several lines of interrogation in one single chart, revealing ranking, magnitude and changes over time.

As a big football fan, this is a particularly interesting time to apply a slopegraph to show the huge amount of transition that has taken place in the Premier League between this season and last.

So far teams have played 15 games. A snapshot of the league tables after 15 games for this season versus last let’s us look at the data and pick out the headline changes in the position of teams in the league and their absolute points,. We can see Arsenal are up at the top of the league having been mid-table last year, as are Liverpool. We can see (and take some delight) in Man Utd’s drop towards mid-table mediocrity but yet they aren’t loads of points away from the precious top 4. We can see Sunderland’s ongoing struggles.



However, it doesn’t satisfactorily draw out the big changes that have happened. The best way to visually expose the big stories of these two contrasting seasons is with the slopegraph. Using data from the official Premier League tables for 2012/2013 (as at 15 games, with manual adjustments for those who hadn’t reached 15) and 2013/2014 (as at 15 games played) we can use something as simple and ubiquitous as Excel to create a simple before and after story. (Note that I have removed the relegated/promoted teams, just using those that were in the league across both seasons.)


Now we can see the stories. Plotting the teams by absolute points totals on the parallel vertical axes automatically encodes their ranking with connecting lines joining the points together highlighting the transition (colour accentuating the up and down movement).

First of all we notice there are clearly big changes, the sloping lines in all directions tell us this instantly. We see how boringly dominant the two Manchester teams were at this point last season: the physical gap between City and third place much more apparent than from the table view. We see Arsenal’s impressive standing, 5 points clear already, and the relative bunching of teams competing for the top places beneath. We see not just Arsenal’s and Liverpool’s rise up the table but the significance of that rise compared to their relative performances at the same stage last year, as it is for Newcastle and Southampton.

To further emphasise the bigger changes up and down we could use the darkness/lightness of colour to visually distinguish those who have gone up or down by 25%+ of their points totals.


Alternatively, we could use the thickness of the connecting line to emphasise this (which might be better for small resolution graphics).


Just a simple demonstration but something that should show the value of a slopegraph in offering multiple insights from a single and simple graphic display. I would love to see this technique being used more, especially in the sports broadcast media, where it could be perfectly deployed.

** Here is a link to a shared Excel file that was used to create these graphs. Feel free to download and view in Excel (ignore the flawed Google preview version of it) **

Best of the visualisation web… October 2013

Game Tree: Visualising Nadal’s historic season

Really like this work from Damien Demaj to visualise a key facet of Rafael Nadal’s incredible 2013 season on the tennis tour. Damien runs GameSetMap, a blog that presents new ways of looking at tennis analytics and tennis spatial data in particular. Damien’s recent work explores Nadal’s historic season via an interactive Game Tree.


Nadal’s Game Tree allows you to explore how his 600+ service games played out in the Grand Slams, Masters 1000 and World Tour Finals. As Damien describes:

The challenge was to come up with a visualization that better reflects game momentum, and therefore shows how easily, or not a player wins their service game. Each point in Nadal’s Game Tree is colour coded to reflect the momentum in each game. Blue representing positive momentum, and red negative momentum. The spine of the game tree is coloured white indicating neutral territory for Nadal.

If it was available, I’d love to see a similar approach applied to all players on the tour, would be fascinating to see the shapes of players throughout the rankings and between genders, see how their games match up to the ideal of that right hand side path on the tree. Maybe you could compare players across small multiples of their basic tree shape? Maybe compare players in different eras?

Anyway, that’s just a personal wishlist, nice work Damien. Check out the rest of his analysis on GameSetMap.

Graphic vocabulary: Charts as words

Just been looking in detail at the latest great project from the NYT’s ‘BosCarQue’ triumvirate, visualising the history of college athletics in the US.


One of the elements that really grabbed me was the integration of a mini bar chart (sparkbars?) within the introduction text.


The idea of creating and embedding word-sized graphics into text is not new. Sparklines, as described below, are one of the most enduring ideas from Tufte’s heyday:

A sparkline is a small intense, simple, word-sized graphic with typographic resolution. Sparklines mean that graphics are no longer cartoonish special occasions with captions and boxes, but rather sparkline graphic can be everywhere a word or number can be: embedded in a sentence, table, headline, map, spreadsheet, graphic. From Edward Tufte’s book Beautiful Evidence.

However, this is the first time I recall seeing it being used ‘in the wild’ (ie. not from Tufte’s texts) and done in a way that seemed so natural, so obvious and so seamlessly, as if a bar chart was just another component of our written vocabulary.
