30 <title>Introduction to Graphviz</title>
31
32 <para>The <application>Graphviz</application> package contains graph
33 visualization software. Graph visualization is a way of representing
34 structural information as diagrams of abstract graphs and networks.
35 <application>Graphviz</application> has several main graph layout
36 programs. It also has web and interactive graphical interfaces, auxiliary
37 tools, libraries, and language bindings.</para>
38
39 <para>The <application>Graphviz</application> layout programs take
40 descriptions of graphs in a simple text language, and creates diagrams in
41 several useful formats such as images and SVG for web pages, Postscript for
42 inclusion in PDF or other documents, or as objects displayed in an
43 interactive graph browser. (Graphviz also supports GXL, an XML dialect.) In
44 practice, graphs are usually generated from external data sources, but they
45 can also be created and edited manually, either as raw text files or within
46 a graphical editor. (Graphviz was not intended to be a
47 <application>Visio</application> replacement, so it would probably be
48 frustrating to try to use it that way.)</para>
49
50 <para>This package is useful for automatic graph drawing which has many
51 important applications in software engineering, database and web design,
52 networking, and in visual interfaces for many other domains. Graphviz has
53 many useful features for concrete diagrams, such as options for colors,
54 fonts, tabular node layouts, line styles, hyperlinks, and custom
55 shapes.</para>

512 <listitem>
513 <para>is a preprocessor to <command>dot</command> that is used to
514 improve the aspect ratio of graphs having many leaves or disconnected
515 nodes. The usual layout for such a graph is generally very wide or
516 tall. <command>unflatten</command> inserts invisible edges or adjusts
517 the minlen on edges to improve layout compaction.</para>

527 <para>supports graph programming by maintaining graphs in memory and
528 reading and writing graph files. Graphs, nodes and edges may be
529 attributed with programmer-defined records and string name-value
530 pairs. Graphs are composed of nodes, edges, and nested subgraphs.

567 <para>maintains directed and undirected attributed graphs in memory
568 and reads and writes graph files. Graphs are composed of nodes,
569 edges, and nested subgraphs. A subgraph may contain any nodes and
570 edges of its parents, and may be passed to any
571 <filename class='libraryfile'>libgraph</filename> function taking a
572 graph pointer, except the three that create new attributes (where a
573 main graph is required).</para>

582 <listitem>
583 <para>supports the use of connected components in the context of
584 laying out graphs using other <application>Graphviz</application>
585 libraries. One set of functions can be used to take a single graph
586 and break it apart into connected components. A complementary set of
587 functions takes a collection of graphs (not necessarily components of
588 a single graph) which have been laid out separately, and packs them
589 together moderately tightly. The packing is done using the polyomino
590 algorithm of K. Freivalds et al.</para>
