Make a libchart directory inside pub/
make sure the libchart directory is world writable (chmod 777 pub/libchart)

Usage

(:chart title='Your Chart' data='1,2,3,4' labels='1,2,3,4' width=400 height=300 type=(HorizontalChart|VerticalChart|PieChart):)

Also supports (:chartdir:) instead of (:chart:) for compatibility with ChartDirector
Width and Height are in pixels
Only data and labels are required, the rest is optional
type must be one of HorizontalChart,VerticalChart,PieChart (case sensitive probably) -- defaults to VerticalChart
The charts are cached for an indefinite time -- delete the files in pub/libchart if you want to regenerate them.

Does not work, neither does chart director - Poor quality code and documentation
PKHG: Got it working, after some small changes ... ;-) 070426:0941
I couldn't get it to work either. Unfortunately, I don't have the expertise to incorporate the "small changes" mentioned above. Could someone help with this? Thanks in advance.
After rebuilding php with a GD library that properly incorporated freetype2, I was able to get libchart working. I've uploaded a new file libchart-1.2-compat.php Δ that reflects the changes I made to get libchart-1.2 (the latest from http://naku.dohcrew.com/libchart/pages/introduction/) working in my setup - YMMV.
