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

  Thanks for the information.  I was looking at using pygdchart2 from 
nullcube.  I was pleased with the interface they've written.  Have you any 
experience with them?  I figured it shouldn't be technically difficult to 
create an interface of parameters that mapped to chart settings.

The only concern I have so far is the method of outputting the chart once 
rendered.  The examples use the draw method:
Draw the graph to the specified file. If the filespec argument is a 
string, it will be treated as the path to a file. Otherwise, filespec is 
assumed to be a Python file object.

I'm new to mod_python, so I'm not sure how to pass the output stream of 
the request object to the draw() method.  If you know, I'm be grateful. If 
not, I'll work at it.  I haven't really dug yet.

btw,   I saw your post earlier about your wiki.  While cruising your site 
I found a MLM I was in need for.  Thanks!

There are several Python graphing packages which you could use towards 
this end, the question is how nicely will they plug into a web 
I am not aware of any that are set up to do this using mod_python.
I'm also busy looking at the problem, for an application we are 
currently converting to be web based, so discuss plans / things you find 
here and I will to and hopefully we can come up with a nice solution...
