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.

If you expand the "Scope" section you'll see more examples. The reason the initial example is restricted is probably because of how noisy those other graphs are when all (or more) movement commands are available. They make poor initial examples.
Noted. Probably the best thing would be simplified color coding in separate graphs showing 3 types of movements from worse to more efficient. And a good statement around what's the point.
Conveying information through images is all about making something understood, not about graph completeness.
