The default is .. code-block:: python ( (Basic, {'color': 'blue', 'shape': 'ellipse'}), (Expr, {'color': 'black'}) ) atom : function, optional Function used to determine if an arg is an atom. A good choice is ``lambda x: not x.args``. The default is ``lambda x: not isinstance(x, Basic)``. maxdepth : integer, optional The maximum depth. The default is ``None``, meaning no limit. repeat : boolean, optional Whether to use different nodes for common subexpressions. The default is ``True``. For example, for ``x + x*y`` with ``repeat=True``, it will have two nodes for ``x``; with ``repeat=False``, it will have one node. .. warning:: Even if a node appears twice in the same object like ``x`` in ``Pow(x, x)``, it will still only appear once. Hence, with ``repeat=False``, the number of arrows out of an object might not equal the number of args it has. labelfunc : function, optional A function to create a label for a given leaf node. The default is ``str``. Another good option is ``srepr``. For example with ``str``, the leaf nodes of ``x + 1`` are labeled, ``x`` and ``1``. With ``srepr``, they are labeled ``Symbol('x')`` and ``Integer(1)``. **kwargs : optional Additional keyword arguments are included as styles for the graph.
