I'm hoping a user who has successfully installed the GraphViz extension can
help me troubleshoot this. You can reply directly to me at <
mpd2002(a)columbia.edu> if you prefer.
I've followed the install
instructions<http://www.mediawiki.org/wiki/Extension:GraphViz>for the
GraphViz extension and so far everything seems OK - GraphViz dot
commands work, permissions look fine - but although the page is parsing the
graphviz content, my wiki page still fails to show any graphics:

Usually there is an error that the map file is not found on line 420 of
GraphViz.php (should be visible on the page linked above). When I look in
the referenced image directory, there's nothing, so I'm guessing that for
some reason the GraphViz extension is not sending output to the GraphViz
image directory, although I don't see anything in the configuration that
would cause problems. (I don't think write access is a problem since I've
granted access to the image directory).
Any idea what's happening? I've looked all over the web and haven't found
anything that helps me troubleshoot.
Unfortunately I'm not good enough with PHP to trace what the extension is
actually doing. Would be grateful for any suggestions.
Sincerely,
