Every network visualization should have a legend that explains what the colors, edge widths, and filters are that define the network graph. NodeXL automatically generates a network legend and displays it when the Graph Elements menu is opened: And the “Legend” option is selected. This will place a legend at the bottom of the visualization [...]

NodeXL allows users to gather vertices into named collections called “Groups”.  This is handy whenever the entities in the network are made up of different types or an algorithm has divided the network into sub-regions based on how densely some vertices connect to one another.  The Groups menu is found in the NodeXL>Analysis menu: Since version [...]
