The book includes attempts to visualize the simulations like modeling a bouncing ball becomes more rewarding if you can see it in action. The tools for animation in Jupiter notebooks using that plot lib are a little bit clumsy, so I didn't get deep into it. But definitely the point where you get to see the simulation and you see the objects moving in space, you I think appreciate it for one thing. If your physical model is doing something incorrect, you're going to see it instantly. It's going to bother you.
