How to use command-line tools and basic GraphViz utilities to
produce graphs both simple and complex.

GraphViz is a collection of tools for manipulating graph structures
and generating graph layouts. Graphs can be either directed or
undirected. GraphViz offers both graphical and command-line tools.
A Perl interface also is available, but it is not covered here for
reasons of generality. Graphical tools are not going to be discussed
in this article either. Instead, this article focuses on using GraphViz
from the command line.

<hr />

The format of a GraphViz command is::

  \\begin{latex}
  \\digraph[Options]{Name}{Specification}
  \\end{latex}

Replace 'Options' with something like 'scale=1.0' and 'Specifications'
with the actual graph, e.g. 'a->b; b->c'. Replace 'Name' with a name
for your graph.

The LaTeX extension for GraphViz (see: LatexTemplate) produces files
named 'Name.dot' and 'Name.ps' in the images working directory. Since
this graph name is global, it is a good idea to prefix the name with
the name of the page on which the graph occurs.

The follow graphs are generated by MathAction

My First Graph::

  !\begin{latex}
  \psfrag{alpha}[cc][cc]{$\alpha$}
  \psfrag{beta}[cc][cc]{$\beta$}
  \psfrag{gamma}[cc][cc]{$\gamma$}
  \digraph[scale=0.75]{GraphVizGraph1a}{rankdir=LR; alpha->beta; beta->gamma}
  \end{latex}

Produces:
\begin{latex}
\psfrag{alpha}[cc][cc]{$\alpha$}
\psfrag{beta}[cc][cc]{$\beta$}
\psfrag{gamma}[cc][cc]{$\gamma$}
\digraph[scale=0.75]{GraphVizGraph1a}{rankdir=LR; alpha->beta; beta->gamma}
\end{latex}

A More Complex Example::

  \\begin{latex}
  \\digraph[scale=0.8]{GraphVizGraph2a}{
      size ="4,4";
      main [shape=box]; /* this is a comment */
      main -> parse [weight=8];
      parse -> execute;
      main -> init [style=dotted];
      main -> cleanup;
      execute -> { make_string; printf}
      init -> make_string;
      edge [color=red];
      main -> printf [style=bold,label="100 times"];
      make_string [label="make a string"];
      node [shape=box,style=filled,color=".7 .3 1.0"];
      execute -> compare;
    }
  \\end{latex}

Produces:
\begin{latex}
\digraph[scale=0.8]{GraphVizGraph2a}{
    size ="4,4";
    main [shape=box]; /* this is a comment */
    main -> parse [weight=8];
    parse -> execute;
    main -> init [style=dotted];
    main -> cleanup;
    execute -> { make_string; printf}
    init -> make_string;
    edge [color=red];
    main -> printf [style=bold,label="100 times"];
    make_string [label="make a string"];
    node [shape=box,style=filled,color=".7 .3 1.0"];
    execute -> compare;
  }
\end{latex}

This::

  }
  \\end{latex}
