Django - Model graphic representation (ERD)

I'm searching a way to represent my Django project model graphically.

Is there a "native" way to do this kind of ERD (diagram) ?

Update following @Etienne instructions

Here is an example of how I finally view the PDF representing some models of my django project

$ python manage.py graph_models app1 app2 ... | dot -Tpdf | evince

• It generates the dot data with my applications (app1, app2, ...)
• Passes the result to dot to output into PDF format
• Opens the output with evince
