Hi this is an attempt to help new contributors having an idea of the speaker fight models.
It was generate using:

./manage.py graph_models organization --output organization.png

I think that this is best to be in Makefile, we are adding a artifact of the project that doesn't have to be versionated with the source and gets old easily.

If you want to convert this to a Makefile command, its okay for me but i dont see any sense in this being versionated, its a compiled file based on a moment in history. For this to be updated we need to on every pull request generate this.
