Citation Map

I would like to be able to build a citation map with my references so that I can visually see the important authors.

The way I see my idea right now is that with in a reference I would list/link other references inside. Then I would “export” a map and see how all my references interface with each other, and the references with the most links are obviously the more important papers, so now I can focus on those papers first. I have attached a sample map from web of knowledge. though this map exists it only operates with one author as the focus I would like to have multiple authors, groups, or entire endnote libraries perform this funtion.
