In this blog post I’ll explain how you can hack a chord diagram to shape it into a more circular looking sankey-like flow chart. Why not just take a regular sankey to visualize the flow? Well, the visualization was meant for use in the media to engage the viewers. Therefore, I wanted to create something visually different. In the end it appears that I just wanted to challenge myself and dive into the d3 source code (for the first time).
In this tutorial, I’ll show you how you can add an invisible voronoi grid over a scatterplot which will improve the experience of the viewer when hovering over the plot. And I’ve actually updated this tutorial in August 2016 when Franck Lebeau came with a great improvement on the final step.
While browsing online I came across several examples of Martin Krzywinski’s Pi art works and I was inspired to try and do a small project with the digits myself. I wanted to try and create something that wasn’t very informative per se, but hopefully pretty to look at, more like art.
