Visual representation of the parts of a Rails application

Question

I've been learning Rails for a few months now and recently realised it would be convenient if there existed some visual "map" of the parts of a Rails application.

Does anything like this exist?

As far as visualizing your own application goes take a look at Rails ERD or Railroad
