''[[Terrain rendering|Terrain visualization]]'': [[VisIt]] can read several file formats common in the field of [[Geographic Information Systems]] (GIS), allowing one to plot raster data such as terrain data in visualizations. The featured image shows a plot of a DEM dataset containing mountainous areas near Dunsmuir, CA. Elevation lines are added to the plot to help delineate changes in elevation.

''Tornado Simulation'': This image was created from data generated by a tornado simulation calculated on NCSA's IBM p690 computing cluster. High-definition television animations of the storm produced at NCSA were included in an episode of the PBS television series NOVA called "Hunt for the Supertwister." The tornado is shown by spheres that are colored according to pressure; orange and blue tubes represent the rising and falling airflow around the tornado.

''Climate visualization'': This visualization depicts the carbon dioxide from various sources that are advected individually as tracers in the atmosphere model. Carbon dioxide from the ocean is shown as plumes during February 1900.

''Atmospheric Anomaly in Times Square'' In the image the results from the SAMRAI simulation framework of an atmospheric anomaly in and around Times Square are visualized.
