Speaking of 3D, it would be cool if this sociogram was a 3D model. Then
we could rotate around whatever we wanted at 360 degrees. Zoom features
would help where the text is illegible. I love these sociograms. It
seems it would be helpful to map out my own social network.

That is a cool idea! Unfortunately the current algorithm is 2D, since I
wanted the map to be easily visible (actually, it is 2D+1, I have a
slight displacement between the planes the subjects and posters lie in).
But I'll see what I can do; making a red/blue map seems quite easy with
this software, and it is ready for full 3D. It could generate a number
of views each time it is run.

A good idea! Right now I try to add a force between nodes that makes
them drift apart if they are at the same height. That doesn't work very
well.

It would look to cluttered (I have tried). I think there is room for
modulation of saturation or value in the posters and subjects, or
perhaps slight shifts in color (but keeping the same rough hue). This
means one scalar each. I will experiment a bit with an estimate of
whether the postings are increasing or decreasing relative to yesterday;
that might be a good scalar.
