I am currently testing with hand-made *positional* data, and do not have an
underlying graph structure yet. I feel that the underlying structure in any
case will go thru a heavy adaption process to visad math and display types,
so this is not a problem.

If you are talking about a visad MathType structure for them, no. I have
tried out two today, but both had problems. If you have suggestions, let me
know.

What primitives and objects do you mean?
