3D Pie Chart Library
This library is an implementation of the Script to 3D pie chart with PHP by Rasmus Petersen - all credits go to him.
My changes
* Accepts data and labels as arrays
* Allows TTF fonts in the labels (optional)
* Handles direct stream output or save to file
Requirements
* GD 2.0.1 or later
* PNG Support
