An Experiment in Collaborative Visualization

Fork, Code, Share - Join the Visualization Sprint

Mar 1, 2012

The Global Water Experiment team went to the folks at with the data set collected through the year-long experiment which involved over 75,000 students in 80 countries collecting water quality samples in their neighborhoods and reporting the measurements back to the Experiment’s website. In keeping with the crowd-sourced origin of this data, has devised a new project: the Visualization Sprint.

The Sprint is an experiment in collaborative data visualization: we challenge our community of creators and coders to work together to visualize the GWE data extracted from The field of data visualization already benefits greatly from open source work, code sharing, debate over technique, and lively design critique. The Visualization Sprint is a new way to promote all of these things. Starting from an initial sketch, created by Jan Willem Tulp using d3.js, anyone is invited to fork the code, change or add to it, and then post it back to the sprint. The idea is that participants will contribute many small modifications — changing a color scheme, adding a key, adjusting the scale — to reach a finished piece collaboratively. However, extensive rewrites or even new “alpha” versions are also welcomed.

With enough participation, this could result in both an awesome visualization and an archived crash course in how to get from a data set to that awesome final product (or products) through many sketches and iterations. This water sample data suggests geographic mapping, so maybe we’ll focus on how best to map multi-dimensional data, or maybe we’ll go in an entirely different direction. Besides the contributions of coders, anyone can participate by voting on what changes work or don’t work and by joining the discussion in the comments.

In order to have a goal in mind, we ask the community to arrive at a finished visualization by World Water Day (March 22), which will then be presented by us and our partners. All participants will get credit on the final visualization(s).

And just to add a little incentive, we’ve teamed up with Eyeo again to offer one pass to this year’s sold-out Eyeo Festival. The winner will be picked at random from everyone who contributes code to the sprint (no bonus for multiple contributions). So head over to the main Sprint page to explore the versions, vote for which contributions you think work, and fork the code.
