Connected Action

I am pleased to announce the return of our network overview, discovery and exploration add-in for Excel 2007 now called NodeXL.

Please visit http://www.codeplex.com/nodexl for the add-in and the source code for the application.

Key features in NodeXL:

> Import data from existing spreadsheets and other network analysis application file formats
> Import data from email reply networks on systems with Windows Search and local stores of email
> Twitter API: pull twitter networks into NodeXL for exploration
> Merge duplicate edges from imported edge lists
> Calculate degree, clustering, and betweenness measures
> Generate subgraph images for every node
> Create clusters for collections of nodes
> Decorate graphs with control over location, color, size, shape or image, and opacity of each edge or vertex
> Dynamic filters: use sliders to filter the graph by multiple dimensions of your data about each edge or vertex
