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 [...]

Starting in version .165 of NodeXL we have supported the idea of an options file that can be imported, exported and exchanged among users. If you have set all the knobs and dials of your copy of NodeXL just right, you can export these adjustments and configurations into a single file.  Use the NodeXL>Options>Export feature [...]

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 [...]

Attractive and well designed network visualization layouts are complex to automate.  Many researchers have devoted a great deal of effort to refining algorithms that assign the best set of positions to a set of nodes.  In many cases a layout algorithm will work well for some types of graphs and not others.  NodeXL has a [...]

As mobile devices become a major method for authoring and consuming social media, location data is increasingly a part of many posts, tweets, check-ins, and messages.  Many Twitter clients, for example, can add the user’s current latitude and longitude to the metadata associated with a tweet.  Other systems like Facebook Places, Google Latitude and Foursquare [...]
