VisIt is an open-source application for large-scale simulated and experimental data sets. The application serves as an infrastructure for parallelized, general post-processing of extremely massive data sets. Its primary use cases include data exploration, comparative analysis, visual debugging,

VisIt is supported by the DOE's SciDAC (Scientific
Discovery Through Advanced Computing) program to assist with the analysis and visualization of large datasets generated by open scientific computing. It is developed in collaboration with multiple organizations, including
