That reminds me of the ternary plots for Condorcet cycles. Let
with x+y+z = 1. Then every feasible such election can be represented by
a set of barycentric coordinates and thus be plotted as a triangle.
On a related note, I imagine that you could make a more general
fingerprint for k-voter elections by placing a space-filling curve in
the appropriate high dimension space and parametrize every point as a
distance along that curve, then reduce to the same curve in say, 2D and
invert the plot to get 2D coordinates.
