    Tried PyChart.  Set up for PNG file format.  Got the error
"Exception: Ghostscript not found."    This thing just creates
PostScript, then pumps it through GhostScript (anybody remember that?)
to get other formats. And does the documentation say that?  Only
in the FAQ section.  Grrr.

    There doesn't seem to be any pure Python chart module at all.
Just wrappers.
