Hm, to verify, is the result page completely empty, or does it look ok
otherwise except that the image is missing?

Some things to check:

Any errors in the web server error log file?

Have you tried without setting the cvsgraph config file in cvsweb.conf?

Did you try from the command line as the user running your web server,
and using the same arguments that cvsweb does?  In your case the image
generation command would be something like:

  cvsgraph -r /path/to/cvsroot \
    -c /usr/local/etc/cvsgraph.conf \
    some/file,v > my.png

The other command to cvsgraph generates the HTML for the imagemap and is
a little more complicated wrt options, see doGraphView() in cvsweb.cgi,
around line 3100.
