I would like to use pylab in a CGI script that would generate a pie
chart/bar graph/…, save it to a file, and then be able to output the
image from the file.
Everything that I’ve tried works if I run
the script from my shell, but when it runs on my test box (or, for that
matter, a sudo without an X display being set up), it gripes about not
being able to open an X display.
Is there a way to either:
1: Tell pylab to run without a display,
2: Configure a dummy display, or
3: Attach the web environment to a real display?
I’m not having it display windows or asking for interesting X functionality–just generate a pie chart and save it as a file.

You probably want to look at this FAQ:
http://matplotlib.sourceforge.net/faq.html#APPSERVER
Or the slightly more updated and elaborate answer in the new (in-progress) docs:
http://matplotlib.sourceforge.net/doc/html/faq/howto_faq.html#how-do-i-use-matplotlib-in-a-web-application-server
