Use python imaging:
http://www.pythonware.com/products/pil/
You can return a response with an image of the graph.
response = HttpResponse(status=200, mimetype="image/gif")
background.save(response, "GIF")
return response
There is no 'best practice for this' Some people i know use flash.
However dynamically generated images is good eg: no browser pluggins
