the "native" dimensionality is one for every user (ie the size of the matrix repr of the graph), not 4, but that's immaterial because the whole point is to shrink it to a manageable number of dimensions. but, it does mean that you can rotate it everywhichway, yeah. imo the best is xy=2d + color=3d
How is it visualized? What is distance and proximity between particles in the picture telling us about accounts? Can our "account particle" travel across this galaxy?
