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.
