Are there any charting or graphing modules for python that can write
PNG, JPEG, or GIF graphics? I have found a couple of nice looking
packages that can make beautiful postscript, PDF, or SVGs (PyChart and
ReportLab) but they can't make PNGs, GIFs, or JPEGs. (On my Solaris
machine with Python 2.2 they don't.) Or are there any simple UNIX
filters to convert SVG, PDF, or ps files to PNG?
