graphviz.sty - A LaTeX library for GraphViz

graphviz.sty allows you to write GraphViz code directly in your LaTeX source.

Prerequisites

You must have the GraphViz program in your path. See http://graphviz.org for more details.

Installation

Copy graphviz.sty to your texmf directory.

LaTeX distribution folder can be found

• On Mac OS X with the MacTeX distribution: ~/Library/texmf/tex/latex
• On Linux it's usually: /usr/share/texmf-texlive/tex/latex/

1. Copy graphviz.sty to you LaTeX distribution folder
2. run $ texhash

Usage

Add the following lines to your preamble:

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

If the options "[pdflatex]" is causing troubles, replace it with

\PassOptionsToPackage{pdftex}{graphicx}
\usepackage{graphicx}

graphviz.sty supports two environments, digraph (which produces oriented graphs):

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

and graphviz for non-oriented graphs:

\begin{graphviz}{MyGraph}
a--b; 
b--c;
\end{graphviz}

Parameters for digraph or graphviz environment:

1. optional parameters:
   • scale -- default value is "scale=1"
   • layout -- for changing graphviz layout filter (possible values "layout=dot|neato|twopi|circo|fdp|sfdp" see graphviz documentation for more details), default is "layout=dot"
   • output -- default is pdf, you can use "output=ps|png|pdf" or which everformat \includegraphics supports. When output is tex graph is converted with dot2tex tool (you have to add tikz package to your preamble) -- this is an experimental feature
2. name of the digraph. This is obligatory argument, it's the name produced output file. If you have two environments with same name file will be overwritten by the later.

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

\includedot[scale=0.5]{mydotfile}

Parameters for \includedot :

1. optional arguments (in [args]) are the same as above
2. name of the dot file (w/out file extension, which must be ".dot")

How to compile

You must use the -shell-escape option for pdflatex. This enables LaTeX to execute system commnds which is for security reasons disabled in most LaTeX distributions by default.

$ pdflatex -shell-escape *.tex

If you are having problems with generating output see LaTeX *.log for this:

runsystem(bash -c "dot -Tpdf graph1.dot > graph1.pdf")...executed.

Using regular LaTeX

To modify this command for regular latex change output to ps

\begin{digraph}[output=ps]{MyGraph}
rankdir=LR; 
a->b; 
b->c;
\end{digraph}

2011-02-21: Modified by Mike Prentice

• use of PDF output directly from dot.
• added includedot layout.

2012-02-17: Modified by Tomas Barton

• Improved check for generated file, allowed backslash and other "unsafe" characted in digraph code
• Added output option
• changed \digraph command to digraph and graph environment which follows much more LaTeX conventions
• supports conversion with dot2tex
