33 The <application>Graphviz</application> package contains graph
34 visualization software. Graph visualization is a way of representing
35 structural information as diagrams of abstract graphs and networks.
36 <application>Graphviz</application> has several main graph layout
37 programs. It also has web and interactive graphical interfaces, auxiliary
38 tools, libraries, and language bindings.
