Custom DOT statements
---------------------
To add arbitrary statements to the created DOT_ source, you can use the
:attr:`~.Graph.body` attribute of :class:`.Graph` and :class:`.Digraph` objects.
It holds the verbatim :class:`list` of (:class:`str`) lines to be written to the source file
(including their final newline).
Use its ``append()`` or ``extend()`` method:
.. doctest::
>>> import graphviz
>>> rt = graphviz.Digraph(comment='The Round Table') # doctest: +NO_EXE
>>> rt.body.append('\t"King Arthur" -> {\n\t\t"Sir Bedevere", "Sir Lancelot"\n\t}\n')
>>> rt.edge('Sir Bedevere', 'Sir Lancelot', constraint='false')
>>> print(rt.source) # doctest: +NORMALIZE_WHITESPACE
// The Round Table
digraph {
"King Arthur" -> {
"Sir Bedevere", "Sir Lancelot"
}
"Sir Bedevere" -> "Sir Lancelot" [constraint=false]
}
.. attention::
Note that you might need to correctly quote/escape identifiers
and strings containing whitespace or other special characters
when using this method.
