From 1c23308299f33e5b429899463eb207f07ad51403 Mon Sep 17 00:00:00 2001 From: Dan McGee Date: Mon, 5 Dec 2011 22:12:09 -0600 Subject: Add developer keys visualization Well, almost add it- it is currently commented out as I have a few more things I'd like to take care of, namely correcting static files versioning and caching, to ensure this doesn't break things. This is a force-directed graph drawn using D3 as the package treemap already does. We color the dots by "group", e.g. "dev", "tu", or "master", and then outline developer keys in green if they have at least 3 master key signatures, red if they have fewer. Hovering over a circle will show you who's key you are seeing in the visualization.
