Back in grad school I used to use an X-Windows program called grtool that
had a simple text based file format for drawing graphs.  It certainly
wasn't XML, but it was extremely useful when I needed to write C code that
chunked out hundreds of pages of graphs for different parameter values.
grtool is probably still out there somewhere.

That job converted me to the text-based file format religion.  It would
have been much harder to do something similar on a Mac or PC using
something like DeltaGraph with its binary file formats.
