Jump to: navigation, search

A mediawiki extension to create graphs in wiki pages, written by Tels. It needs a few perl modules to be installed via cpan, esp. it uses Graph:Easy and can output graphs as ASCII, HTML or SVG.


  • Graph::Easy is up to date (0.53).
  • Installed wikimedia-graph 0.21

Looks a lot better now, thanks Tels.

You can create graphs like this:
