I recommend GD::Graph by CPAN author MVERB I am quite happy with the pie charts it generated for the work I am doing at this site: http://www.angryman.com, you can sort results by criteria and see some actual charts it generated. But, you must get GD from http://www.boutell.com and then GD.pm from CPAN author LDS and then GD::Chart and then let the good times roll.
