From various platforms (Unix, Linus, Windows or Mac workstations) users can interactively visualize and analyze data ranging in scale from small (<101core) desktop-sized projects to large (>105 core) leadership-class computing facility simulation campaigns.Users can quickly generate visualizations, animate them through time, manipulate them with a variety of operators and mathematical expressions, and save the resulting images and animations for presentations.

VisIt contains a rich set of visualization features to enable users to view a wide variety of data including scalar and vector fields defined on two- and three-dimensional (2D and 3D) structured, adaptive and unstructured meshes.
