visone provides many algorithms for network analysis; all of them are accesible via the analysis tab. Basic illustrations of how to analyze networks and subsequently display the computed values are provided in the two trails on visualization and analysis and advanced attribute management.

visone distinguishes between three major analysis tasks

  • indexing for the computation of node-level and edge-level properties, such as centrality;
  • grouping for the computation of specific groups of nodes and/or links, such as densely connected clusters;
  • siena for modeling network dynamics via the RSiena package. (See the trail on using RSiena from within visone for illustration of this task.)
