Positively, VisAD is very dynamic.  Here are a few examples:

1. The visad/examples/VisuTraj.java program recently
contributed by Christian Mullon, shows particle trajectories
under brownian motion.

2. The visad/aune/ShallowFluid.java is a steerable 2-D
shallow fluid model (note, it only runs on Sparc Solaris
because of native Fortran code).

3. Any of the direct manipulation examples, such as
visad/examples/Test00.java, and CurveManipulationRendererJ3D.java,
CollectiveBarbManipulation.java and FlexibleTrackManipulation.java
in visad/bom.

In answer to your particular point, if multiple data objects
are linked to a display and only one of them changes, then only
that one is replotted.

Cheers,
Bill
