Thanks!

To avoid some typing, you can achieve the same writing:

Sizing the resulting graph can be a bit tricky. Here are your alternatives:

- Alter the graph size using DOT attributes. I have to admit that I'm
not very familiar with how the various attributes work, so you have to
take a look in the Graphviz documentation for more information.

- Creating a standalone PDF of you graph and include it using
\includegraphics[width=\textwidth]{..}.
You can do this relatively easy using:

And then you can write:
\includegraphics[width=\textwidth]{dot_file}

- Scale the tikzpicture environment.The generated code is put inside a
tikzpicture environment:

\begin{tikzpicture}[options]
...
\end{tikzpicture}

To scale the graph you can use the options:
\begin{tikzpicture}[scale=2,transform shape]
...
\end{tikzpicture}
Since you use the tikz output format you can also do things like:
\begin{tikzpicture}[xscale=1.5,yscale=2]
...
\end{tikzpicture}
to stretch the graph without altering the node sizes. If you want to
scale the nodes, you have to add the transform shape option.

To add additional options to the tikzpicture environment you have two options:
1. Use the --graphstyle command line option:

2. Use the special d2tgraphstyle attribute:

digraph G{
d2tgraphstyle="scale=2,transform shape";
a -> b;

Hope this helps. For experimentation my dot2tex(i) latex package is
useful. Then you can do everything within your latex document:

% ---
\documentclass{article}
\usepackage{tikz}
\usepackage{dot2texi}

\begin{document}

\begin{tikzpicture}[scale=2,transform shape]
\begin{do2tex}[mathmode,autosize,codeonly]
digraph G {
a -> b -> c;

\end{tikzpicture}

\end{dot2tex}
\end{document}
%----

Hope this helps!
