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 [...]

In many cases I look at a network graph and apply a series of operations to transform it into a more presentable form.  For example, I often calculate graph metrics, use Autofill columns to map data to display attributes like size, color, or shape, create clusters, sub-graph images, and then select the Harel-Koren layout and [...]
