GEXF and GDF are common file formats for network data. NodeXL now (v.405) imports and exports GEXF and GDF files natively. This means that archives of network data sets stored in these formats can be easily opened, analyzed, and visualized in NodeXL with just a few clicks.

New: MediaWiki Importer in NodeXL Pro
Wikis on the MediaWiki platform contain many kinds of networks: pages link to pages, categories link to categories, and users link to pages, among others. It is now easy to extract these networks for analysis and visualization using the NodeXL MediaWiki Network Importer.
This importer is now a default feature of NodeXL Pro.
Using this importer we can, for example, map the connections among the Wikipedia pages that connect to the page for "Social Media" revealing clusters, themes, and central related pages.
This month's featured network leverages the NodeXL Twitter LIST importer to show interactions among Members of the German Bundestag in Twitter over a time frame of 10 days in early October 2018. The politicians are colored by party affiliation, gray disks represent Twitter accounts outside the Bundestag.
It is interesting to see that the Clauset-Newman-Moore cluster algorithm places members of B90/Die Grünen and Die Linke into one single group (G1). Also members of CDU/CSU and FDP are clustered into one single group (G2), while members of SPD (G3) and AFD (G4) each form one dominant group.
The above network map is part of our research project "Mapping Political Networks". Read more about it in our recent blog post and have look at related network maps in the NodeXL Graph Gallery.
This is our first offering of a monthly NodeXL Pro license combined with the computer, operating system, and Office suitepreloaded and installed - ready to use from almost any connected device with a web browser.
Any connected tablet, phone, Mac, Linux, or even underpowered Windows PC can now access NodeXL Pro via a powerful remote virtual machine that is fully preconfigured and ready to roll powered by our partners at Intact.Digital.
Academic and student users can "roll your own" version of NodeXL Pro Cloud Edition by creating an Amazon EC2 Virtual Machine and copying Office and NodeXL into it.
