In the most recent prior release of NodeXL we added new metrics that describe networks in terms of their number of components and the length of paths in those networks.  In this release we automate creation of histograms of network metrics.  It is useful to see the distribution of attributes like in-degree or betweenness to [...]

Network visualizations can be very compelling but they are often a smear of unintelligible nodes and edges without refinement and filtering.  Creating an automated layout for a complex graph is a challenging area of mathematics and computer science.  Several layouts are available and are widely implemented, including the Fruchterman-Reingold layout, the Harel-Koren fast multilevel layout, [...]

There are hundreds of conferences sponsored by the ACM on almost every topic related to computing.  In some cases the same person will publish a paper in more than one conference, creating a tie between them.  Below is a network map application that displays a collection of ACM conferences connected by this authorship tie: [...]

NodeXL has had a rudimentary flickr tag network data spigot for some time but we have just added a number of features to this data importer that makes it much more useful.
You can now select the number of network levels to include, an optional sample image file can be included for each tag, and the [...]

On December 4th, I will be attending the Oxford Internet Institute’s Forum on Relationships and the Internet which will feature researchers focused on computer-mediated relationships.  Rather than being used primarily to access information, people often use networked computing to access people, creating or sustaining relationships with others.  There are many ways in which the Internet [...]
