I would like to be able to cause Gephi to display a hull around any three nodes that I specify. Is this possible?
Why? In my networks, in some cases there is a dependency between an edge and a node elsewhere in the network. That is, there is a data associated with the edge, and this data is a function of data associated with a node that is not one of the endpoints of the edge. Let's call this "third" node the "controlling node". I'm looking for ways to turn on and off a graphical representation of this relationship. Putting a hull around the endpoints of an edge and the controlling node that it's associated with would provide a convenient way to show this relationship. However, I'm open to other methods.
(One way that the relationship between the edge and the third node is represented in the GEXF data file is that controlling node has a label of the form "x=y", where "x" and "y" are the labels of the nodes that are endpoints of the associated edge. However, I can program the GEXF-generating code to add any attributes that would make it more convenient to generate the hulls I want.)
Thanks.
