Sexual Relations Graph – Best Use of a Visual

  Sexual Relations Graph

The best use of a visual at the Net2 conference so far IMHO was from Martin Kearns. This graph (to the right and here) is titled "Structure of Romantic and Sexual Relations." 

Staying with the sexual social networks metaphors, it is apparent that Kevin Bacon gets around.

In the diagram note the large cluster on the top left. That is called a spanning tree diagram. All it would take to add more of those lonely trees to the primary tree is one connection.

A quick google search leads me to believe this is the original study from Jefferson High School.
