Network analysis and visualization software

  • R is a powerful open source statistical computing application. It has easy scripting, visual output, and data analysis. Network analysis is easy with the igraph package (see below).
  • Agna is another Java based tool with a nice interface for data entry/editing, and a separate window for visualization and layout.
  • Gephi an open-source, cross platform tool for network exploration. Makes beautiful, highly customizable, plots.
  • GUESS is a powerful visualization and analysis tool written with Python.
  • Tulip is open source and written with Qt/C++/OpenGL and has a lot of interesting, interactive features, not to mention a beautiful logo. The interface is very creative, and documentation is extensive.
  • SocNetV is an open-source graph manipulation/visualiation appliation for Linux, built with C++ and Qt (Qt4 package required) with a simple graphical interface. Easy to use, keeps it simple.
  • SoNIA is a Social Network Image Animator, and can be used to create interesting layouts, as well as videos of evolving networks.
  • NetworkX is an open-source, terminal-based python program with simple commands and lots of features for manipulation and visualization of graphs.
  • Network Workbench is a powerful application written in Java with lots of analysis tools, though the interface is not very friendly.
  • Pajek (old) is a popular layout and analysis tool that has a lot of good features. It is, however, only for Windows, and is not open source.
