Graphics: Libchart
Jean-Marc Trémeaux (contact me)
This package can be use to generate graphical images with charts of several types.
There is one base chart class and several sub-classes for implementing charts of the types: bar, pie, horizontal and vertical bars, etc...
There are also auxiliary classes for drawing text labels and axis lines.
It uses PHP GD and FreeType library functions to render the image graphics.
