Stratopan’s interactive dependency graphs are a great way to visualize and explore the relationships between Perl modules (see example below). So we teamed up with Olaf Alders and the MetaCPAN gang to provide graphs for the entire Perl community. You will now find a link to the graph on the right side of the page under the dependency list for nearly every release on MetaCPAN.
In fact, you can embed the graphs in any web page. So now you can add graphs to your blog, POD, or README files on GitHub, or anywhere else! All you need is one line of markup.
Special thanks to David Farrell at PerlTricks for inspiring this idea.
