alt Hacker News> In the example, why would you even move with single chars and not words or to the end of line?
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.
