New page

Dot is part of the Graphviz group of programs.

It is similar in some ways to LaTeX, in that you start with a text document written with a particular syntax, and then run it through dot to process it and generate images (pdf, png, jpeg, etc) as the output.

=Installation=

Dot can be downloaded from here: http://graphviz.org/Download.php

Binaries for most platforms are provided, as well as source code.

=Usage=

Use the example dot file given below. This should be put in a file like <code>plot.dot</code> or something similar:

<pre>
digraph G {
CFD
"Governing equations"
CFD -> "Governing equations"
"Discretization of governing equations"
CFD -> "Discretization of governing equations"
CFD -> "Fluid mechanics"
Turbulence
"Fluid mechanics" -> Turbulence
Turbulence -> "Turbulence modeling"
"Turbulence modeling" -> RANS
LES
"Turbulence modeling" -> LES
"Turbulence modeling" -> DNS
}
</pre>

This file is written in "dot" syntax. Next, this file will be processed through dot. Two things must be specified: first, the format of the output image, and second, the output file.

Use the following command:

<source lang="bash">
dot plot.dot -Tpng -o plot.png
</source>

Alternatively, you can specify:

<source lang="bash">
dot plot.dot -Tpng -O
</source>

which will use the name of the input file and change the extension to match the format (in this case, <code>plot.png</code>).

Dot supports the following output formats:

* png
* gif
* ps
* svg
* svgz
* fig

and some less common formats:

* cmapx
* imap
* mif
* hpgl
* pcl

See http://www.graphviz.org/cvs/doc/info/output.html for more info.
