graphviz 0.3.1

Simple Python interface for Graphviz

Latest Version: 0.4.8

This package facilitates the creation of graph descriptions in the DOT language of the Graphviz graph drawing software from Python.

Create a graph object, assemble the graph by adding nodes and edges, and retrieve its DOT source code string. Save the source code to a file and render it with the Graphviz installation of your system.


This package runs under Python 2.7 and 3.3+, use pip to install:

$ pip install graphviz

To render the generated DOT source code, you also need to install Graphviz (download page).

Make sure that the dot executable is on your systems’ path.


Create a graph object:

>>> from graphviz import Digraph

>>> dot = Digraph(comment='The Round Table')

>>> dot  #doctest: +ELLIPSIS
< object at 0x...>

Add nodes and edges:

>>> dot.node('A', 'King Arthur')
>>> dot.node('B', 'Sir Bedevere the Wise')
>>> dot.node('L', 'Sir Lancelot the Brave')

>>> dot.edges(['AB', 'AL'])
>>> dot.edge('B', 'L', constraint='false')

Check the generated source code:

>>> print(dot.source)  # doctest: +NORMALIZE_WHITESPACE
// The Round Table
digraph {
    A [label="King Arthur"]
    B [label="Sir Bedevere the Wise"]
    L [label="Sir Lancelot the Brave"]
        A -> B
        A -> L
        B -> L [constraint=false]

Save and render the source code, optionally view the result:

>>> dot.render('test-output/round-table.gv', view=True)
