Any anytree graph can be converted to a graphviz graph.

This tree:

>>> from anytree import Node
>>> root = Node("root")
>>> s0 = Node("sub0", parent=root)
>>> s0b = Node("sub0B", parent=s0)
>>> s0a = Node("sub0A", parent=s0)
>>> s1 = Node("sub1", parent=root)
>>> s1a = Node("sub1A", parent=s1)
>>> s1b = Node("sub1B", parent=s1)
>>> s1c = Node("sub1C", parent=s1)
>>> s1ca = Node("sub1Ca", parent=s1c)

Can be rendered to a tree by RenderTreeGraph:

>>> from anytree.dotexport import RenderTreeGraph
>>> RenderTreeGraph(root).to_picture("tree.png")
