+#+BEGIN_QUOTE

+#+END_QUOTE
+
+For the last weeks, I've been working on the successor of
+[[http://cpan-explorer.org/][CPAN Explorer]]. This time, I've decided to
+create some visualizations (probably 8) of the various communities using
+[[http://github.com/][GitHub]]. I'm happy with the result, and will soon
+start to publish the maps (statics and interactives) with some analyses.
+I'm publishing two previews: the Perl community and the european
+developers. These are not final results. The colors, fonts, and layout
+may change. But the structure of the graphs will be the same. All the
+data was collected using the [[http://developer.github.com/][GitHub
+API]].
+
+Each node on the graph represents a developer. When a developer
+"follows" another developer on GitHub, a link between them is created.
+The color on the Perl community map represent the countries of the
+developer. One of the most visible things on this graph is that the
+japanese community is tighly connected and shares very little contact
+with the foreign developers. miyagawa obviously acts as a glue between
+japanese and worldwide Perl hackers.
+
+The second graph is a little bit more complex. It represents the
+European developers on GitHub. Here the colors represent the languages
+used by the developers. It appears that ruby is by far the most
+represented language on GitHub, as it dominates the whole map. Perl is
+the blue cluster at the bottom of the map, and the green snake is...
+Python.
+
+Thanks to [[http://code.google.com/p/tinyaml/][bl0b]] for his
+suggestions :)
