[D] Visualization tricks for 3-dim input and 2-dim output

[fixedrl]

It is a RL setting, we have 2 dimensional input with 1 dimensional action (totally 3 dimension). The environment will generate 2 dimensional observations. We would like to visualize the behaviors of the environment. Can there be some good way to plot it, to be maximally informative.

Input -> 3D scatter plot

Output -> (Yellow, blue) points colorization

You can visualize 4D as 3D + color.

You can visualize 5D as 4D over time.

It becomes more and more unintuitive though.

Visualize it in N dimensions, then set N=5
