With JPGraph being one of the more standard choices out there for graphing with PHP, it's always nice to find another project whos graphs look just as nice (if not nicer) - GraPHPite.

GraPHPite is pronounced "graphite", as in the layered hexagonal structure of carbon. It is an acronym of Graph and PHP and 'ite to make it pronouncable.

It uses PHP4 or 5 with GD 2 support to get the job done (GD 1.x is supported, but then it doesn't support all features) and includes lots of chart types, the ability to pull from several data sources, gradient color fills, and much, much more.

If you do a lot of graphing in PHP, you might want to give this nice-looking library a try...
