From the post:
VisIt is a free interactive parallel visualization and graphical analysis tool for viewing scientific data on Unix and PC platforms. Users can quickly generate visualizations from their data, animate them through time, manipulate them, and save the resulting images for presentations. VisIt contains a rich set of visualization features so that you can view your data in a variety of ways. It can be used to visualize scalar and vector fields defined on two- and three-dimensional (2D and 3D) structured and unstructured meshes. VisIt was designed to handle very large data set sizes in the terascale range and yet can also handle small data sets in the kilobyte range.
I’m not promising what your results will be but samples to show what is possible:
Raleigh-Taylor instability
The featured visualization shows a Pseudocolor plot that highlights a Raleigh-Taylor instability caused by two mixing fluids.

Multiple plots
VisIt can put multiple plots in a single visualization, allowing you to visualize data in multiple ways. The featured image shows four representations of Mount St. Helens elevation data from a DEM file.
The DEM dataset used to create the featured image was obtained from the USGS.
Do you support annotation of graphics with your topic map engine?
