``neato`` no-op flag
--------------------
The `neato <DOT neato_>`_ layout engine
supports an additional `rendering flag <neato no-op_>`_
that allows more control over the node positioning and the edge layout
via the `pos <DOT pos_>`_,
`overlap <DOT overlap_>`_,
and `splines <DOT splines_>`_ attributes.
Use the ``neato_no_op`` keyword argument of
:meth:`~.Graph.render` or :meth:`~.Graph.pipe`
to pass it to the layout command:
.. doctest::
>>> doctest_mark_exe() # skip this line
>>> import graphviz
>>> n = graphviz.Digraph(name='splines', engine='neato',
... graph_attr={'splines': 'true'},
... node_attr={'shape': 'point'})
>>> n.node('a', pos='0,0!', color='blue')
>>> n.node('b', pos='100,0!', color='green')
>>> n.node('c', pos='50,50!', color='red')
>>> n.edge('a', 'b', pos='0,0 30,66 70,60 100,0')
>>> n.render(neato_no_op=2, directory='doctest-output').replace('\\', '/')
