Overview Do you need to display and analyze a network graph but you don’t want to deal with difficult applications, arcane file formats, or advanced programming languages? NodeXL may be what you’re looking for. NodeXL is a template for Excel 2007 that lets you enter a network edge list, click a button, and see the network graph, all in the Excel window. You can easily customize the graph’s appearance; zoom, scale and pan the graph; dynamically filter vertices and edges; alter the graph’s layout; find clusters of related vertices; and calculate a set of graph metrics. Networks can be imported from and exported to a variety of data formats, and built-in connections for getting networks from Twitter, Flickr, YouTube, and your local email are provided. If you are new to network graphs, you can find a network graph overview here<http://en.wikipedia.org/wiki/Graph_theory> . ------------------------------ The NodeXL Template in Action This is what the NodeXL template looks like. In this example, a simple two-column edge list was entered into the Edges worksheet, and the Show Graph button was clicked to display the network graph in the graph pane on the right. [image: NoAttributes.png] The two-column edge list is all that’s required, but you can extensively customize the graph’s appearance by filling in a variety of optional edge and vertex columns. Here is the same graph after color, shape, size, image, opacity, and other columns were filled in.
