How to use the database query diagram when developing a Django app in Pycharm Professional?

I notice that one of the new features of the recently released version of Pycharm Professional is being able to show a database query diagram, but I'm a bit stumped when it comes to using it when developing a Django application. What I would like to do is on every request to a view to automatically show a database query diagram so I can get an idea of what needs to be optimised in my application.

To be honest, I'm relatively new to working with PostgreSQL, so I'm somewhat confused. I am using Django Debug Toolbar which has a minimal version of this feature, but I'd like to use the functionality built into Pycharm.

Any help is appreciated.
