Each row of this data frame represents a pair of characters who had a sexual relationship on the TV show Mad Men, as of the end of season 4. This data can be displayed with an undirected graph.
The placement of names in column Name1 as opposed to Name2 is arbitrary, and not meaningful. In other words, for any row, you can swap the values of Name1 and Name2, and it will represent the same information.
Name1: Name of one sexual partner.
Name2: Name of another sexual partner.
