Joint Mathematics Meetings has quite a number of interesting videos on math, but the one where I found their channel was this one, Daniel Spielman on “Miracles of Algebraic Graph Theory”. Presents, among other things, a demonstration of why the first eigenvectors of some graph representation or other (I have to rewatch it every damn time to remember exactly which one) end up being an analytical solution to force-directed graph drawing. https://www.youtube.com/watch?v=CDMQR422LGM—https://www.youtube.com/channel/UCKxjz1WXZOKcAh9T9CBfJoA
