I've used GD::Graph for simple 'business graphics' (pie charts, bar graphs etc) and it works quite well for those things. Also GD is nice for redering simple buttons etc.

I've used Gimp for 'complex' graphics redering like semi-transparent text on background images with all kinds of filters. It's really good and very flexible but it did take me quite a long time to work out (not to mention the problems of installing everything on an X-less webserver).

I've also used GraphViz for creating nice, renderings of graphs - the kind with nodes and vertices. The perl interface is nice and seems stable, but not 100% complete as far as I can see.

There is a lot of stuff on CPAN i've never used, so maybe somebody else kan post his/her experiences here...

HTH, Joost
