I've succeeded in adding custom <data> elements to my GraphML file and linking them to the label of a node using the properties mapper. However, the GraphML contains nested graphs which also have that attribute specified. I would like that attribute to be used as a Label in the Group heading.
I have not yet seen how to map to a group heading label. Is this even possible or should I replicate all of the XML that yEd generates in order to put a label on a group?
Thanks in advance,
