[mod_python] does a mod_python handler exist to generate charts/graphs? (png images)

Hello everyone,
   I was about the go down the road of developing a handler to generate 
charts,
similar to the mod_perl Apache::GD::Graph.  I wanted to make sure 
something doesn't exist
before I reinvent the wheel.  Does anyone know of such a thing yet?  If 
so, would you please
provide a url?

Thanks,
Perry Tew
