I've had good success with GD::Graph [1] at a previous job, and at my current
job we've used Chart [2], which has a somewhat cleaner look. Unfortunately
(as of 3 months ago) GD::Graph appeared to be more actively maintained than
Chart, since we submitted a patch for some legend placement options, and 
never heard back. Also GD::Graph has better support for TrueType fonts. 
While it's name doesn't reflect it, Chart uses GD just as GD::Graph does, 
but in a perhaps more elegant way. Chart comes with some very nice PDF
documentation however, which is pretty useful for this sort of module.
