Hi, I've been using PyQtGraph for a while and it's great!

Of course, it has a deep/interwoven hierarchy of classes (important for reusability and flexibility). Sometimes it is not absolutely clear how to put them together when you're building things from scratch (as opposed to just copying and modifying examples!).

This documentation page is immensely helpful, but only offers a partial view, focused on the graphics layout and a handful of classes:

http://www.pyqtgraph.org/documentation/plotting.html#organization-of-plotting-classes

Many classes and ways to compose things are missing. Would it be possible to complement this page with a complete diagram of the class hierarchy? Especially relationships like "can be a child of" are super useful when creating new graphics from scratch, and to have a "big picture" of sorts. I would offer to do it but my knowledge of the full class hierarchy is piecemeal and limited.
