## Class SiteGraph

- java.lang.Object
- - org.apache.struts2.sitegraph.SiteGraph

-     public class SiteGraph
      extends Object

  SiteGraph is a tool that renders out GraphViz-generated images depicting your Struts-powered web application's flow. SiteGraph requires GraphViz be installed and that the "dot" executable be in your command path. You can find GraphViz at http://www.graphviz.org.

  If you wish to use SiteGraph through its API rather than through the command line, you can do that as well. All you need to do is create a new SiteGraph instance, optionally specify a `Writer` to output the dot content to, and then call `prepare()`.
