What are Network Data Visualizations?

Network Visualizations are a good choice for data that cannot be easily captured using a tree structure. In addition to simply showing where items connect, users often want to know about shortest or least costly paths connecting two items or transversing the entire network.

Examples of network visualizations include: adjacency list, node-link diagram, hive plot, dependency graph, alluvial diagram, matrix, and subway map

Tools for Network Visualizations


A free, open-source template for Microsoft® Excel® 2007 and 2010 that makes it easy to explore network graphs.  With NodeXL, you can enter a network edge list in a worksheet and click a button to see your graph, all in the familiar environment of the Excel window.
