Earlier quoted context omitted.
OP here -- that is a fantastic anecdote! Do you have an example of a "drawing" of a theorem, in this context? (I've seen these for fairly trivial theorems but not for more complex ones, so I'm curious.)
I think a good example would be Lagrange's theorem[0]. Once you have this[1] picture in mind, it becomes trivial. [0] https://en.wikipedia.org/wiki/Lagrange%27s_theorem [1] https://i.stack.imgur.com/w2GfA.png
Was it this theorem of Lagrange's that you had in mind https://en.wikipedia.org/wiki/Lagrange%27s_theorem_(group_th... ?
