Moin Tels,
I would like to integrate "Graphviz" extension in ZUM-Wiki (www.zum.de/wiki).
I cannot help you with the Graphviz extension (at least not much), but I can help you installing the graph extension, which is, IMHO (but I am biased :) much better suited for a wiki:
http://bloodgate.com/perl/graph/ http://bloodgate.com/perl/graph/manual/
thanks. But "Graph" seems not to offer the same graphical possibilities like "Graphviz" does.
Regards Karl
