For drawing graphs you can have a look at google graph api 
(http://code.google.com/apis/chart/)

I've once used another cart libray offering API in different languages
see : http://www.advsofteng.com/product.html

And then there is GD::Graph, but I have no experience with this. 
For basic graphic functions look  at Imager (imager.perl.org)
