This can be done with graphviz, there is a ready-made solution for Django models available in the django-extensions
3rd party module here:
http://django-extensions.readthedocs.org/en/latest/graph_models.html
…hmm, on second thoughts I guess you’re probably not using Django models but rather App Engine datastore models (and not NDB models judging by your old version). Try this:

I have used the django graphviz before with success, have not tried modelviz personally.
