Visualize higher-order Observables

[crunchie84]

Currently the switchMap is not visualised as awesome as the rest

Do you mean that it does not have the colorful dot's inside the marble diagram? I want to make several improvements to this visualization that would change this example:

• make clear which lines in the structure are direct relations and which are higher order
• group observables created inside the switchMap initially
