Hi,

When I try to execute, I have the following error (on macOS) :

@ldb2000 if you are using brew to install graphviz then it looks like you need to install with: brew install graphviz --with-pango

See https://stackoverflow.com/questions/48383874/graphviz-crashes-on-mac-during-render-using-quartz and Homebrew/homebrew-core#18684
