Question for March 2 - PS

We've had lots of "whats this map" style questions, here's a small twist, a "whats this graph" question.


The above graph was part of a paper in 2004 in the American Journal of Sociology, by researchers from Columbia and Washington. The paper, and specifically this graph, got lot of media attention, and subsequently was studied by researchers in diverse other fields.

Identify the graph (try to be as specific as possible).

I think this graph connects people based on sexual relationships between them. The two colours, I suppose, indicate male and female. The preponderance of connections between points of opposite colours and presence of hubs are my main clues.

Is it got to do with how 2 people are inter-related or connected to eachother

There are not a lot of lines from blue to blue and from pink to pink. So I'm going to guess graph of sexual relationships among people (some sample set, probably college students given the amount of promiscuity).

Blue = male, Pink = female.

This is a graph of the sexual habits of students from some high school. The blue dots are buys and the pink dots are girls, and a line indicates sexual activity between them.

Its a graph mapping the romantic and sexual relationships of an entire high school (Jefferson High School) over 18 months. It provided evidence that these adolescent networks don't have hubs that cause the "small world" effect, like researchers previously thought. Instead they have a giant component in the form of one long chain.

Congrats Rahul, Nikhil, Sailesh.
