    Soo.... this actually turns out to be pretty neat:) From my model
    below, adding

    100: pageConfiguration = GraphVizPayment => visibleEntityNames = (

       "PaymentChannelType"
    )

    yields:



    Note that it automatically creates the missing nodes.

    Sweet. One *could* make it so it uses the tools directly and return
    the PDF. Right now it only creates the .dot file and you still have to
    open it in the GV app.

    Cheers, Anjo
