Very nice concept; a mvp
Just on first glance: 1. first diagram and others, ball jumps from beginning of BtoA arc to B without sliding along the arc.
2. second diagram box was no P(B|B). That is boxes are mislabeled.
3. strange, but arcs are sometimes at an angle. It appears to happen if they are scrolled to, but no if drawn on the initial screen.
4. while the R S on the next diagram does settle to a steady state, it starts with random Rs and Ss marching across at random rates.
Good Start!
