I started a simple little app to display a Graphviz diagram based off
the Django models.

It's simple and not so purty, but it's a start. It also requires
graphviz to be installed and in the path.

Install to to your Django server like any other app and the url will
then be http://localhost/diagram/<app name>.

Any suggestions are welcome.

You might a settings option to specify the graphviz path. Fall back
to assuming it's already there if the setting isn't available.

Sorta like JING_PATH:

If you're intending for this to be used outside of development, stash
the results of dot generation in cache. Maybe have a url parm that
invalidates the cache for the rare non-dev model changes.
