I spent a few hours looking at charting app, d3-force simulation.
Steve Haroz's ds-force testing ground program has interface sliders, for a number of the force choices.
Output is SVG graphics. It has a multiple sliders input panel, and is live.

The output would have to be converted to MoI planar geometry, and input would be a bunch of circles.
Maybe a MoI script could be done, with users able to manipulate the circles on the screen, with the mouse?
Or Nodeeditor?

There seem to be no boundaries, nor3d surfaces...
Maybe a bunch of anchored circles could form boundaries?
I read that there are 40,000 d3 examples. A bunch with d3 force.
One has the circles "afraid" of the mouse. Phylotaxis layout is a default.
Connecting Links, (lines, also called edges), is not needed...

Anyway, it was fun.
I think I will go back to some other projects now.
