Co-Authors are people in Profiles who have published together.
This cluster graph shows the co-authors (green circles) and top co-authors of co-authors (blue circles) of Michael Callahan (red circle). The size of a circle is proportional to the number of publications that author has. The thickness of a line connecting two authors' names is proportional to the number of publications that they share. Options for customizing this network view are listed below the graph.
