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 <application>Graphviz</application> basic usage does not need any
78 libraries out of what is found in the LFS book. Its <quote>core</quote>
79 rendering engine allows 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 for example tools from
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 to first build
88 it without any dependencies, then to rebuild it when you have built
89 enough packages to suit your needs.
