When networks overlap each other (e.g., poles 1--2--3--4, where 1 connects to 3 and 2 connects to 4) the current visualizer can cause confusion when visualizing all networks. This can of course be mitigated by only visualizing hovered networks, but it'd be neat if there'd be some special method of highlighting the hovered network(s). Changing the color drastically might be complicated with how the colors can be customized, but maybe outlining the visualized network(s)?

Additional suggestion would be to outline all networks, with the hovered network(s) rendering last to place it on top, which I imagine looking something like the following: https://imgur.com/a/aLGdgwr

I think the additional suggestion would remove the need for the brightness randomization setting. Much easier for me to notice the overlaps with the outlines than the color randomization differences.
