I'd like to submit this has no practicality from a Vim tutorial perspective. However, from the perspective of anyone wanting to learn about graph theory and who understands the concepts of typing efficiency incorporated in Vim key movements, this could be very interesting.
Kind of like many other things using Wolfram - a personal notebook that someone found interesting or useful, take it or leave it.
Analyzing the typing experience in vim by looking at pure keystrokes would be a mistake if you don't understand the tradeoffs and benefits of having a modal system and operating the editor without leaving the home row or needing a mouse.
Good remappings/config would also significantly alter your experience.
In the example, why would you even move with single chars and not words or to the end of line? I think it's definitely a poor example because the point of the diagram/investigation is not clearly described.
