Galaxy Chart in D3

When I first started working in for the Deputy CIO for Business Process & Systems Review, I was exposed to a data visualization called a “galaxy chart“. The version I saw was developed by Technomics, Inc., who (interestingly) do a lot of work for my former organization, PA&E (now CAPE).

While Technomics seemed to claim (when I met them) that they “invented” the galaxy chart, I think this is probably an overstatement, since there seems to be plenty of prior art.

Anyhow, I built a D3 plugin for a galaxy-chart layout.
