graphviz.sty lets you include GraphViz dot files directly in your LaTeX source.

graphviz.sty is currently only compatible with pdflatex.

You must have the GraphViz dot program in your path.

Copy graphviz.sty to your texmf directory.

On Mac OS X with the MacTeX distribution:

1. Make folder ~/Library/texmf/tex/latex if it doesn't already exist.
2. Drag and drop graphviz.sty to that folder.

Or for the Terminally ill:

$ mkdir -p ~/Library/texmf/tex/latex
$ cp graphviz.sty ~/Library/texmf/tex/latex

Add the following lines to your preamble:

\usepackage[pdftex]{graphicx}
\usepackage{graphviz}

To include GraphViz dot syntax directly in your LaTeX source:

\digraph[scale=0.5]{MyGraph}{rankdir=LR; a->b; b->c}

Parameters to \digraph:

1. parameters for \includegraphics (optional; default value is "scale=1")
2. name of the digraph
3. body of the digraph

To include an external GraphViz dot file named mydotfile.dot:

\includedot[scale=0.5]{mydotfile}

Parameters to \includedot:

1. parameters for \includegraphics (optional; default value is "scale=1")
2. name of the dot file (w/out file extension, which must be ".dot")

You must use the -shell-escape option to pdflatex:

$ pdflatex -shell-escape mydoc.tex

To modify this command for regular latex, replace all .pdf with .ps, and the command becomes simply:

dot -Tps #2.dot

Graphvizzz on Google Code includes support for graph as well as digraph.

graphviz.sty is based on graphviz.tex by Derek Rayside (2003).
