Something puzzles me about this request.
"Graph" produces device-independent UNIX PLOT(4) data.
UNIX PLOT(4) does not define 3-D graphic primitives,
although they have been added at BRL.

What would your 3-D equivalent of "graph" DO without
3-D primitives?  How would you view them if you had them?
(At BRL, we have one 3-D PLOT(4) device, and I'm planning
on producing a DMD 3-D interactive viewer "soon".)
