[ENH] Make more compact edges when ORUI starts

[maikol-solis]

Is your feature request related to a problem? Please describe.

When I start ORUI, i can see some nodes spread all over the graph with edges going from side to side.

This causes unnecessary overlaps in the nodes and edges.

Describe the solution you'd like
Manipulating manually the nodes and rearranging them, I can get a setting like this one

Ideally, the user shouldn't be rearranging the nodes to have this effect when the server starts. Maybe a new physics option, or adjusting the existing ones by default, can achieve this effect.

Thanks.

The setting you might want to play with is the Stabilization Rate under "Physics > Advanced". I cranked it up quite a bit from the default to improve performance, but there might be some merit in having it be a little higher on startup.
A better solution I would think would be to save the layout of the graph itself. I'll implement that eventually, probably!
