Graphviz
========

This package facilitates the creation and rendering of graph descriptions in
the DOT_ language of the Graphviz_ graph drawing software (`upstream repo`_)
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 `Jupyter notebooks`_ (formerly known as
`IPython notebooks`_,
`example <notebook_>`_, `nbviewer <notebook-nbviewer_>`_)
as well as the `Jupyter QtConsole`_.

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

This package runs under Python 3.8+, use pip_ to install:

.. code:: bash

    $ pip install graphviz

To render the generated DOT source code, you also need to install Graphviz_
(`download page <upstream-download_>`_,
`archived versions <upstream-archived_>`_,
`installation procedure for Windows <upstream-windows_>`_).

Make sure that the directory containing the ``dot`` executable is on your
systems' ``PATH``
(sometimes done by the installer;
setting ``PATH``
on `Linux <set-path-linux_>`_,
`Mac <set-path-darwin_>`_,
and `Windows <set-path-windows_>`_).

Anaconda_: see the conda-forge_ package
`conda-forge/python-graphviz <conda-forge-python-graphviz_>`_
(`feedstock <conda-forge-python-graphviz-feedstock_>`_),
which should automatically ``conda install``
`conda-forge/graphviz <conda-forge-graphviz_>`_
(`feedstock <conda-forge-graphviz-feedstock_>`_) as dependency.


Quickstart
----------

Create a graph object:

.. code:: python

    >>> import graphviz  # doctest: +NO_EXE
    >>> dot = graphviz.Digraph(comment='The Round Table')
    >>> dot  #doctest: +ELLIPSIS
    <graphviz.graphs.Digraph object at 0x...>

Add nodes and edges:

.. code:: python

    >>> dot.node('A', 'King Arthur')  # doctest: +NO_EXE
    >>> 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:

.. code:: python

    >>> print(dot.source)  # doctest: +NORMALIZE_WHITESPACE +NO_EXE
    // 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 (skip/ignore any ``doctest_mark_exe()`` lines):

.. code:: python

    >>> doctest_mark_exe()  # skip this line

    >>> dot.render('doctest-output/round-table.gv').replace('\\', '/')
    'doctest-output/round-table.gv.pdf'

Save and render and view the result:

.. code:: python

    >>> doctest_mark_exe()  # skip this line

    >>> dot.render('doctest-output/round-table.gv', view=True)  # doctest: +SKIP
    'doctest-output/round-table.gv.pdf'

.. image:: https://raw.github.com/xflr6/graphviz/master/docs/_static/round-table.svg
    :align: center
    :alt: round-table.svg

**Caveat:**
Backslash-escapes and strings of the form ``<...>``
have a special meaning in the DOT language.
If you need to render arbitrary strings (e.g. from user input),
check the details in the `user guide`_.
