PILGraph Upgrade or Alternative Suggestion

[Roger]

Anyone have an updated version of PILGraph beyond 0.1a7 or a suggestion 
for a light-weight alternative?

By light-weight I mean something that doesn't require many/any packages 
other than PIL and will create plain old round pie-chart PNG graphics 
with titles and legends.  I do need multi-platform for both Linux and 
Windows.  The intended use is to create graphics for web pages on the fly.

TIA,

Roger
