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

76 <para>
77 Basic usage of <application>Graphviz</application> does not require any
78 libraries out of what is found in the LFS book. Its <quote>core</quote>
79 rendering engine is able to generate several graphic formats, such as
80 Postscript, SVG, VML, .fig, and Tk. Those formats can be converted
81 to almost any other format using tools from packages such as
82 <xref role="nodep" linkend="imagemagick"/>. The dependencies below add
83 the ability to generate graph images in bitmap format, to display the
84 graph image on screen, to edit a graph by viewing the resulting image
85 directly, or to view large graphs. Since
86 <application>Graphviz</application> is a dependency
87 of several other packages in this book, it is suggested that you first
88 build it without any dependencies, and then rebuild it when you have
89 built enough packages to suit your needs.
