I’d like to recommend Prof Chern’s course on Discrete Differential Geometry https://cseweb.ucsd.edu/~alchern/teaching/cse270_wi24/. The lecture slide on Exterior Calculus includes many good illustrations of differential forms, and there are more cool figures on related topics. There is also a pdf textbook neatly formatted if you want to dive deeper.
