Proposal: 3D plots

[alexlenail]

Perhaps the plotting tool I have always wanted most is a robust, manipulable, 3D plotting tool, like CAD for data.

• It should provide the ability to embed points, curves (and lines), surfaces (and planes), and arrows (think vectorfield) together in 2D or 3D.
• It should do a really good job of projecting high dimensional objects (points, lines, surfaces) into lower dimensional spaces (PCA, t-SNE, arbitrarily defined subspaces).
• It should beautifully animations between these different subspaces / views.
• It should provide a nice UI to color objects by different attributes / values on the objects.

What prior art can we find which already solves some or all of this problem? @jonathanzong

I'm finding that the plotly plot editing UI is really nice -- the only limitation I can find is it doesn't seem obvious how to add multiple types of objects (e.g. surfaces and points) in the same figure

This leads me to believe perhaps the more general problem has been well solved by plotly / others, and perhaps it's better to focus on the narrow problem for computational biology.
