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