I think the field of automata has some lovely diagrams.

I'm sure many are familiar with state diagrams, directed graphs that can be used to explain regular expressions or any other FSM

Turing machines also can be represented with a diagram featuring a "tape" - so elegant

Professor Rick Thomas made a great impression on me whilst lecturing on the subject of Automata
