edgetarget
Browser window to use for the
edgeURL link
type: escString, default: <none>
If the edge has a URL or edgeURL
attribute, edgetarget determines which window of the
browser is used
for the URL attached to the non-label part of the edge.
Setting edgetarget=_graphviz will open a new window if it
doesn't already exist, or reuse it if it does.
If undefined, the value of the target is used instead.
