NodeXL is a free, open-source template for Microsoft® Excel® 2007, 2010 and 2013 that makes it easy to explorenetwork graphs. With NodeXL, you can enter a network edge list in a worksheet, click a button and see your graph, all in the familiar environment of the Excel window.
Visit the NodeXL Graph Gallery to see the wide variety of graphs that have been created by the NodeXL community.
What's New
In the latest release, the Twitter Users Network feature now allows you to limit the network to the specified users.
NodeXL will now automatically update itself when a new release becomes available.
See the Complete NodeXL Release History for details.
NodeXL Features
- Flexible Import and Export Import and export graphs in GraphML, Pajek, UCINet, and matrix formats.
- Direct Connections to Social Networks Import social networks directly from Twitter, YouTube, Flickr and email, or use one of several available plug-ins to get networks from Facebook, Exchange, Wikis and WWW hyperlinks.
- Zoom and Scale Zoom into areas of interest, and scale the graph's vertices to reduce clutter.
- Flexible Layout Use one of several "force-directed" algorithms to lay out the graph, or drag vertices around with the mouse. Have NodeXL move all of the graph's smaller connected components to the bottom of the graph to focus on what's important.
- Easily Adjusted Appearance Set the color, shape, size, label, and opacity of individual vertices by filling in worksheet cells, or let NodeXL do it for you based on vertex attributes such as degree, betweenness centrality or PageRank.
- Dynamic Filtering Instantly hide vertices and edges using a set of sliders—hide all vertices with degree less than five, for example.
- Powerful Vertex Grouping Group the graph's vertices by common attributes, or have NodeXL analyze their connectedness and automatically group them into clusters. Make groups distinguishable using shapes and color, collapse them with a few clicks, or put each group in its own box within the graph. "Bundle" intergroup edges to make them more manageable.
- Graph Metric Calculations Easily calculate degree, betweenness centrality, closeness centrality, eigenvector centrality, PageRank, clustering coefficient, graph density and more.
- Task Automation Perform a set of repeated tasks with a single click.
NodeXL for Programmers
The NodeXL template displays graphs using a custom Windows Presentation Foundation (WPF) control that can be reused in custom applications. In fact, the template is just an application wrapper around a set of reusable, prebuilt class libraries. Check theDownloads tab for the latest version of the class libraries.
You can create a .NET assembly that will import graph data from a custom source into the NodeXL template. These "plug-ins" appear in NodeXL's Data, Import menu. SeeFor Programmers: About NodeXL Graph Data Providers for details.
