ParaView is the open-source, multi-platform data analysis and visualization application that we recommend. It enable the user to quickly build visualizations to analyze data using qualitative and quantitative techniques. It is a very good tool to analyze extremely large datasets using distributed memory computing resources and can be run on supercomputers as well as on laptops for smaller data.
Installing:
Windows: go to http://www.paraview.org/download/ and download the version compatible to your operational system.
Linux: you can install directly from your repository typing:

However some new versions of operational systems can present some compatibility problems, so that in this case we suggest you to download the binary file from http://www.paraview.org/download/.
