This library now accepts an optional
graphviz.name
attribute that will be used as the name (or ID) for the root graph object in the DOT output if given. Unless explicitly assigned, this will now be omitted by default. It is common to assign aG
here, but usually there should be no need to assign this. Among others, this may be used as the title or tooltip in SVG output.Supersedes / closes #20, thank you @rhelms
