[Question] - Extract AST to Graphviz

I was wondering if there is an way people have found to extract the Spoon AST into an existing graph format like GraphViz. I noticed there is a [GraphVisPrettyPrinter](https://github.com/INRIA/spoon/blob/master/spoon-control-flow/src/main/java/fr/inria/controlflow/GraphVisPrettyPrinter.java) in the controlflow project. Is there something similar for the AST?
