[EM] Graphing calculator or software

[Steve Barney]

I am now reading _The Basic Geometry of Voting_, by Donald Saari, and could use
something which would model a 3 or 4 boundary unit simplex, and graph a point
or vector. Is anyone here familiar with any freeware or shareware which can
handle that.

Thank you,
SB
