To draw diagrams, you need to build UnionSets of Gridded2DSets
with manifold dimension = 1, as in visad/examples/Rivers.java.
VisAD is primarily aimed at numerical data, but can handle diagrams.
You can also find some examples of drawing Shapes, as in
visad/examples/Test47 and Test46, and visad/bom/TrackManipulation.java.
Shapes can be used for special shapes at diagram junctions and leaves.
Good luck,
Bill
