Essential Resources: Tools for collecting and handling data

This is part of a series of posts to share with readers a useful collection of some of the most important, effective and practical data visualisation-related resources. This post presents a collection of useful tools, resources and references for gathering, cleaning and preparing your data for analysis and design.

Please note, I may not have personally used all the packages or tools presented but have seen sufficient evidence of their value from other sources. Whilst some inclusions may be contentious from a quality/best-practice perspective, they may still provide some good features and provide value to a certain audience out there. Finally, to avoid re-inventing the wheel, descriptive text may have been reproduced from the native websites if they provide the most articulate descriptions. Your feedback is most welcome to help curate this collection, keep it up to date and preserve its claim to be an essential list of resources!
