[Enhancement] "Bird's Eye View" of operations

[tesseralis]

One problem that I have with the current polyhedra viewer is that it's hard for users to really tell how an operation "moves" you across the map of polyhedra. The set of polyhedra is a graph connected with operations as edges:

However, it's not clear when doing operations on polyhedra that this "movement along the graph" is happening. I want to find a way to make this more apparent, like having a "map" of the entire graph visible in a corner (like how code editors have a minimap). Or perhaps, this requires rethinking how the app is laid out in its entirety.
