If your conceptual model is the oscilloscope, that is to say
time traces of scalar quantities, then I would put it up in a
Java 2D frame. If you want to show time-dependent spatial
quantities or functions of more than one variable, then Java 3D
is the answer. I've seen many effective ways to approach it,
from a simple Excel-style 3D plot to projections of spatial data
onto planes or shapes. Depends on the content and your intended
audience.
