Newbie with a data problem

[cws5157]

I'm working on a SNA of students who attend the University of North Georgia. It is a multi-campus university. I have the campuses and the students' random ID in the nodes table along with the x,y coordinates of the centroid of their county of origin.

In the edges table, I have attributes about their major, year, county of origin.

I have been able to show the distribution using the geo layout plugin, but my question is: How do I break out the clusters of each student in each county based on these various attributes? They are only showing as one node.
