Introduction

pydot allows you to write graphs in the dot language.


---------------------------------------------------------------------
Requirements

* python 2.7


---------------------------------------------------------------------
Installation

To install pydot into your home directory type the following:

$ python setup.py test install --home ~/.local

If you haven't already extended your local python path then add the following
to your environment configuration script. For example to your ~/.bashrc:

$ export PYTHONPATH=~/.local/lib/python:$PYTHONPATH


---------------------------------------------------------------------
Code Example

The following example shows how to write a simple directed graph into a file:

import pydot

with open('dgraph.dot', 'w') as f:
     dot = pydot.DotWriter(f)

     dot.writeGraphBegin('myGraph')

     dot.writeVertex('First Vertex', color = 'red')
     dot.writeVertex('Second Vertex', color = 'green')

     dot.writeEdge('First Vertex', 'Second Vertex', color = 'blue')

     dot.writeGraphEnd()

The code above should write someting like the following to the file
'dgraph.dot':

digraph myGraph {
        vFirst_Vertex [label="First Vertex" color=red]
        vSecond_Vertex [label="Second Vertex" color=green]
        vFirst_Vertex -> vSecond_Vertex [ color=blue]
}
