While I appreciate the effort the author has clearly put in here, Im not sure the visualization provides much in the way of practical intuition. These seem to essentially be mechanistic explanations of the rote bits of matrix math.

There are already rich geometric interpretations which provide useful intuition for that generalizes, rather than just demonstrating mechanical details.
