With this PR, I intorduce diagrams representation for the PySimpleGUI project to help new contributors orient themselves in the codebase.
You can see how the proposed changes render here:

PySimpleGUI has nearly 2k forks -> many developers are exploring the codebase—likely focusing on specific components. That’s why we think that diagram-first documentation can help - with it users can quickly locate the part they care about and understand how it fits into the larger system. What’s your take on this approach?

I'd usually open a discussion first, but you don't have them enabled for this repo so I decided to go ahead and open a PR.

Any feedback is more than welcome!

Full transparency: we’re exploring this idea as a potential startup, but we’re still early and figuring out what’s actually useful to developers.
