Supreme Court Graphic

Last Saturday's New York Times' coverage of Supreme Court Justice Sandra Day O'Connor's resignation included this very effective graphic, showing the extent of (dis)agreement among Supreme Court Justices. The size of the circle shows the extent of agreement between two particular justices, and the distance between any two justices shows the extent of agreement between them.

This graphic can be used effectively to illustrate pair-wise agreement or correlation among any type of variable, such as interaction affects among different media. I recommend it.
