StackOverflowError when calling toFile #237

I am using version 0.18.1 and I get a StackOverflowError when trying to output to a file. Here's a minimal example to reproduce the problem: MutableGraph graph = mutGraph("example1").setDirected(true).add( mutNode("a").add(Color.RED).addLink(mutNode("b"))); Graphviz.fromGraph(graph).height(100).render(Format.PNG).toFile(file);

Error message is below.
