GraphViz extension not working

[donatelloOo]

Following error occurs when using GraphViz extension with basic example.

Cf. http://www.sphinx-doc.org/en/master/usage/extensions/graphviz.html

For example:

digraph foo {
   "bar" -> "baz";
}

Outputs:

# Python version: 3.6.6 (CPython)
# Docutils version: 0.14

Thanks for your patience. Will be fixed in 0.5.0.
