1	1	=========
2	2
3	3
	4	Version 0.17
	5	------------
	6
	7	Drop Python 2 support. Tag Python 3.10 support.
	8
	9	Migrate CI to GitHub actions. Add ``pypy3`` to matrix.
	10
	11	Tests: implement ``--skip-exe`` via custom ``pytest`` marker.
	12
	13	Documentation: point Anaconda users to ``conda-forge/python-graphviz``.
	14
	15	Move type hints from docstrings to type annotations. Improve doctests.
	16
	17	Examples: standardize import convention and modernize.
	18
	19	Re-render example notebooks with Graphviz 2.46.1.
	20
	21
	22	Version 0.16
	23	------------
	24
	25	Add ``.unflatten()`` method to ``Graph``, ``Digraph``, and ``Source``. Add
	26	standalone ``unflatten()``.
	27
	28	Make ``Source.__str__()`` return the ``.source`` instead of the ``repr()``
	29	(like ``Graph`` and ``Digraph``).
	30
	31	Render with ``dot -K<engine> ...`` instead of ``<engine> ...`` internally
	32	(work around `upstream issue
	33	<https://gitlab.com/graphviz/graphviz/-/issues/1753>`_).
	34
	35	Add documentation hint to archived upstream version for Windows.
	36
	37	Re-render most documentation graphs with Graphviz 2.44.1.
	38
	39
	40	Version 0.15
	41	------------
	42
	43	``Graph`` and ``Digraph`` instances created via the context-manager returned
	44	by ``subgraph()`` now (re)use ``directory``, ``format``, ``engine``, and
	45	``encoding`` from the parent instead of using defaults (behavioral change).
	46	Note that these attributes are only relevant when rendering the
	47	subgraph independently (i.e. as a stand-alone graph) from within the
	48	``with``-block, which was previously underdocumented (PR BMaxV). To reflect that
	49	the DOT language does not allow subgraph statements to specify ``strict``
	50	(i.e. no way to override the setting of the containing graph), instances
	51	created via the context-manager are now ``strict=None`` instead of ``False``
	52	(so they continue to render stand-alone as non-strict by default).
	53
	54	Drop Python 3.5 support and tag Python 3.9 support.
	55
	56	Add documentation link to new upstream installation procedure for Windows.
	57
	58
4	59	Version 0.14.2
5	60	--------------
6	61
7		Adapt `graphviz.version()` to support the Graphviz Release version entry format
8		introduced with `2.44.2` (`version()` is needed to run the tests).
	62	Adapt ``graphviz.version()`` to support the Graphviz Release version entry
	63	format introduced with ``2.44.2`` (``version()`` is needed to run the tests).

18		This package facilitates the creation and rendering of graph descriptions in
19		the DOT_ language of the Graphviz_ graph drawing software (`master repo`_) from
20		Python.
21
22		Create a graph object, assemble the graph by adding nodes and edges, and
23		retrieve its DOT source code string. Save the source code to a file and render
24		it with the Graphviz installation of your system.
25
26		Use the ``view`` option/method to directly inspect the resulting (PDF, PNG,
27		SVG, etc.) file with its default application. Graphs can also be rendered
28		and displayed within `Jupyter notebooks`_ (formerly known as
29		`IPython notebooks`_, example_) as well as the `Jupyter Qt Console`_.

43		Installation
44		------------
45
46		This package runs under Python 2.7, and 3.5+, use pip_ to install:
47
48		.. code:: bash
49
50		$ pip install graphviz
51
52		To render the generated DOT source code, you also need to install Graphviz
53		(`download page`_).
54
55		Make sure that the directory containing the ``dot`` executable is on your
56		systems' path.
57
58
59		Quickstart
60		----------
61
62		Create a graph object:
63
64		.. code:: python
65
66		>>> from graphviz import Digraph
67
68		>>> dot = Digraph(comment='The Round Table')
69
70		>>> dot #doctest: +ELLIPSIS
71		<graphviz.dot.Digraph object at 0x...>
72
73		Add nodes and edges:
74
75		.. code:: python
76
77		>>> dot.node('A', 'King Arthur')
78		>>> dot.node('B', 'Sir Bedevere the Wise')
79		>>> dot.node('L', 'Sir Lancelot the Brave')
80
81		>>> dot.edges(['AB', 'AL'])
82		>>> dot.edge('B', 'L', constraint='false')
83
84		Check the generated source code:
85
86		.. code:: python
87
88		>>> print(dot.source) # doctest: +NORMALIZE_WHITESPACE
89		// The Round Table
90		digraph {
91		A [label="King Arthur"]
92		B [label="Sir Bedevere the Wise"]
93		L [label="Sir Lancelot the Brave"]
94		A -> B
95		A -> L
96		B -> L [constraint=false]
97		}
98
99		Save and render the source code, optionally view the result:
100
101		.. code:: python
102
103		>>> dot.render('test-output/round-table.gv', view=True) # doctest: +SKIP
104		'test-output/round-table.gv.pdf'

29	50	Basic usage
30	51	-----------

39	60
40	61	.. code:: python
41	62
42		>>> from graphviz import Digraph
43
44		>>> dot = Digraph(comment='The Round Table')
	63	>>> import graphviz
	64
	65	>>> dot = graphviz.Digraph(comment='The Round Table')
45	66
46	67	>>> dot #doctest: +ELLIPSIS
47	68	<graphviz.dot.Digraph object at 0x...>

108	129
109	130	.. code:: python
110	131
111		>>> from graphviz import Graph
112
113		>>> g = Graph(format='png')
	132	>>> g = graphviz.Graph(format='png')
114	133
115	134	You can also change the :attr:`~.Graph.format` attribute on an existing graph
116	135	object:

133	152
134	153	.. code:: python
135	154
136		>>> h = Graph('hello', format='svg')
	155	>>> h = graphviz.Graph('hello', format='svg')
137	156
138	157	>>> h.edge('Hello', 'World')
139	158

160	179	:class:`.Graph` and :class:`.Digraph` objects have a
161	180	:meth:`~.Graph._repr_svg_`-method so they can be rendered and displayed
162	181	directly inside a `Jupyter notebook`_. For an example, check the
163		``examples/notebook.ipynb`` file in the
164		`source repository/distribution <notebook.ipynb_>`_ (or the same rendered
165		within nbviewer_).

	183	`source repository/distribution <graphviz-notebook.ipynb_>`_ (or the same
	184	rendered within nbviewer_).
166	185
167	186	This also allows direct displaying within the `Jupyter Qt Console`_ (e.g.
168	187	`the one <spyderconsole_>`_ inside `Spyder IDE`_):

	547	:meth:`~.Source.render`, :meth:`~.Source.view`, etc. with the same API
	548	(minus modification, see details `below <Using raw DOT_>`_).

17
18		This package facilitates the creation and rendering of graph descriptions in
19		the DOT_ language of the Graphviz_ graph drawing software (`master repo`_) from
20		Python.
21
22		Create a graph object, assemble the graph by adding nodes and edges, and
23		retrieve its DOT source code string. Save the source code to a file and render
24		it with the Graphviz installation of your system.
25
26		Use the ``view`` option/method to directly inspect the resulting (PDF, PNG,
27		SVG, etc.) file with its default application. Graphs can also be rendered
28		and displayed within `Jupyter notebooks`_ (formerly known as
29		`IPython notebooks`_, example_) as well as the `Jupyter Qt Console`_.

43		Installation
44		------------
45
46		This package runs under Python 2.7, and 3.5+, use pip_ to install:
47
48		.. code:: bash
49
50		$ pip install graphviz
51
52		To render the generated DOT source code, you also need to install Graphviz
53		(`download page`_).
54
55		Make sure that the directory containing the ``dot`` executable is on your
56		systems' path.
57
58
59		Quickstart
60		----------
61
62		Create a graph object:
63
64		.. code:: python
65
66		>>> from graphviz import Digraph
67
68		>>> dot = Digraph(comment='The Round Table')
69
70		>>> dot #doctest: +ELLIPSIS
71		<graphviz.dot.Digraph object at 0x...>
72
73		Add nodes and edges:
74
75		.. code:: python
76
77		>>> dot.node('A', 'King Arthur')
78		>>> dot.node('B', 'Sir Bedevere the Wise')
79		>>> dot.node('L', 'Sir Lancelot the Brave')
80
81		>>> dot.edges(['AB', 'AL'])
82		>>> dot.edge('B', 'L', constraint='false')
83
84		Check the generated source code:
85
86		.. code:: python
87
88		>>> print(dot.source) # doctest: +NORMALIZE_WHITESPACE
89		// The Round Table
90		digraph {
91		A [label="King Arthur"]
92		B [label="Sir Bedevere the Wise"]
93		L [label="Sir Lancelot the Brave"]
94		A -> B
95		A -> L
96		B -> L [constraint=false]
97		}
98
99		Save and render the source code, optionally view the result:
100
101		.. code:: python
102
103		>>> dot.render('test-output/round-table.gv', view=True) # doctest: +SKIP
104		'test-output/round-table.gv.pdf'
105
106		.. image:: https://raw.github.com/xflr6/graphviz/master/docs/round-table.png

	40	This package facilitates the creation and rendering of graph descriptions in
	41	the DOT_ language of the Graphviz_ graph drawing software (`upstream repo`_)
	42	from Python.
	43
	44	Create a graph object, assemble the graph by adding nodes and edges, and
	45	retrieve its DOT source code string. Save the source code to a file and render
	46	it with the Graphviz installation of your system.
	47
	48	Use the ``view`` option/method to directly inspect the resulting (PDF, PNG,
	49	SVG, etc.) file with its default application. Graphs can also be rendered
	50	and displayed within `Jupyter notebooks`_ (formerly known as
	51	`IPython notebooks`_,
	52	`example <notebook_>`_, `nbviewer <notebook-nbviewer_>`_)
	53	as well as the `Jupyter QtConsole`_.

	67	Installation
	68	------------
	69
	70	This package runs under Python 3.6+, use pip_ to install:
	71
	72	.. code:: bash
	73
	74	$ pip install graphviz
	75
	76	To render the generated DOT source code, you also need to install Graphviz_
	77	(`download page <upstream-download_>`_,
	78	`archived versions <upstream-archived_>`_,
	79	`installation procedure for Windows <upstream-windows_>`_).
	80
	81	Make sure that the directory containing the ``dot`` executable is on your
	82	systems' path.
	83
	84	Anaconda_: see the conda-forge_ package
	85	`conda-forge/python-graphviz <conda-forge-python-graphviz_>`_
	86	(`feedstock <conda-forge-python-graphviz-feedstock_>`_),
	87	which should automatically ``conda install``
	88	`conda-forge/graphviz <conda-forge-graphviz_>`_
	89	(`feedstock <conda-forge-graphviz-feedstock_>`_) as dependency.
	90
	91
	92	Quickstart
	93	----------
	94
	95	Create a graph object:
	96
	97	.. code:: python
	98
	99	>>> import graphviz
	100	>>> dot = graphviz.Digraph(comment='The Round Table')
	101	>>> dot #doctest: +ELLIPSIS
	102	<graphviz.dot.Digraph object at 0x...>
	103
	104	Add nodes and edges:
	105
	106	.. code:: python
	107
	108	>>> dot.node('A', 'King Arthur')
	109	>>> dot.node('B', 'Sir Bedevere the Wise')
	110	>>> dot.node('L', 'Sir Lancelot the Brave')
	111
	112	>>> dot.edges(['AB', 'AL'])
	113	>>> dot.edge('B', 'L', constraint='false')
	114
	115	Check the generated source code:
	116
	117	.. code:: python
	118
	119	>>> print(dot.source) # doctest: +NORMALIZE_WHITESPACE
	120	// The Round Table
	121	digraph {
	122	A [label="King Arthur"]
	123	B [label="Sir Bedevere the Wise"]
	124	L [label="Sir Lancelot the Brave"]
	125	A -> B
	126	A -> L
	127	B -> L [constraint=false]
	128	}
	129
	130	Save and render the source code, optionally view the result:
	131
	132	.. code:: python
	133
	134	>>> dot.render('test-output/round-table.gv', view=True) # doctest: +SKIP
	135	'test-output/round-table.gv.pdf'
	136
	137	.. image:: https://raw.github.com/xflr6/graphviz/master/docs/round-table.png
