Authors
We used data available from the CPANTS database to reconstruct the relationships between developers inside the CPAN.

Nodes
A graph node is an author : a Perl developer having commited a distribution (a software library) to CPAN.
An edge is a relationship between two authors : one (or both) of these two authors relies on the package developed by the other.
Layout
We used a force-directed based layout algorithm on the graph. Each node is affected by a repulsion force by all other nodes, except for nodes having a connection with him (attraction force).
As a result, the stronger the relationship is (ie. more packages involved), the nearest the two authors will be.
Some special authors
- Gisle Aas (main developer of
LWPandURI) - Dave Rolsky (
DateTime,Moose, …) - Adam Kennedy (> 200 dists)
- Michael Schwern (
MakeMaker,Test::*) - Ingy (
YAML,Kwiki,IO::All, nearly 100 modules) - Stevan Little (
