Wow, it seems like Japan is the second most popular country (after the US) with 8%. It is not clear 8% of what, but I had no idea there was so much open-source programming in Japan. I rarely hear about Japanese programming efforts.

Another note: I wish it was possible to zoom into these pictures. Because right now it's like looking at a ball of cotton. EDIT: Sorry, I didn't notice the "All Sizes" options in Flickr.

Perhaps it may get the http://cpan-explorer.org/ treatment?

In meantime I just clicked on each picture which brought me to the flickr page and downloaded the largest image.

I will try to publish dynamic map soon, so you can search people on the graphs.

Excellent stuff franck, look forward to it... though I did manage to find myself quite easily just next to Miyagawa :)

My vanity has kicked in and I want to know where my name is in the Ruby map. I can see myself in the downloaded .gdf file, but don't understand the coordinate system. Can someone explain it to me?

Update: I downloaded Gephi and poked around, but haven't yet found a search feature. Still looking...

The coordinate system is obtained from a force-directed algorithm. Iteratively linked nodes attract each others, whereas non-linked repulse.

And to search, go to the "Data Laboratory" and filter. Right-click on a row and "Select on graph". Then go back to the graph, the camera is centered on the node.

Found it. Thanks.

I've noticed the author used Gephi:

Dynamic exploration of the graphs ? (http://github.com/jbilcke/tinaweb)

Wow, so cool. For some reason I've shown up on the Python list rather than Ruby.

Impressive!

Yep. Also from same author is http://cpan-explorer.org/
