StatViz is a simple program to help visualize the way visitors use your web site. This is sometimes called clickstream or path analysis. Unlike traditional web statistics, the output of StatViz is a graph. The file format of the graph file is DOT. These files can be visualized using GraphViz. StatViz analysis is a supplement to traditional log analysis, not a replacement. StatViz produces 2 main reports: 1) Top Referrer Pairs - shows you the most common internal clicks on your site, and also the most common aggregate click paths on your site. 2) Session Analysis - generates separate reports for actual individual user sessions so you can trace exactly how individuals navigate your site. StatViz analysis helps you improve navigation on your site and improve "weaknesses" in your site.
