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.

103 <para>
104 <application>Graphviz</application> basic usage does not need any
105 libraries out of what is found in the LFS book. Its <quote>core</quote>
106 rendering engine allows to generate several graphic formats, such as
107 Postscript, SVG, VML, .fig, and Tk. Those formats can be converted
108 to almost any other, using for example tools from <xref role="nodep"
109 linkend="imagemagick"/>. The dependencies below add the ability to
110 generate graph images in bitmap format, to display the graph image on
111 screen, to edit a graph by seeing directly the result image, or to view
112 large graphs. Since <application>Graphviz</application> is a dependency
113 of several other packages in this book, it is suggested to first build
114 it without any dependencies, then to rebuild it when you have built
115 enough packages to suit your needs.
