Well, some people have been crazy enough lately to generate more or less imageless bar graphs though, see Eric Meyer's "Bar Graphs with Style" (http://meyerweb.com/eric/thoughts/2005/12/20/bar-graphs-with-style/) for more informations on the subject (http://meyerweb.com/eric/css/edge/bargraph/demo.html for a demo) -- http://mail.python.org/mailman/listinfo/python-list
