You're right, I should bave added more animations since what I'm saying is not obvious. I'll try to make sure that there aren't any places like this in my future videos.
Great video. Does much better job (to explain the algorithm / proof) than any 30 min / one hour video on Vizing's theorem. Some details are kinda "left to check for the student" but the proof is all there.
I was about to comment about the audio and pacing, but realized it was recommended after having watched your latest video. Congrats on the progress! It's a lot better
