as Title, is any possible to do that?
I create a diagram use LayeredDigraphLayout, and found setting location by binding the loc attribute at nodeDataArray was useless, if setting the layout.isInitial = false, it trun out all the node must have real location to display.
Yes you can set on a specific node that it does not participate in the layout by setting isLayoutPositioned to false. You will want to set a location on that one node, of course.
The Arrowheads sample for example uses a circular layout, but the center node of the has this property set, since it is not part of the circle.
