graphviz 0.4.7

Simple Python interface for Graphviz

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.

Use the view option/method to directly inspect the resulting (PDF, PNG, SVG, etc.) file with its default application. Graphs can also be rendered and displayed within IPython notebooks.


This package runs under Python 2.6, 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)
