This Demonstration presents a general method for using GraphPlot as a basis for illustrating details of categorical interconnections in the elements of a set. In this case, each of the forty-three individuals who has served as U.S. President is further categorized as having held other elected, commissioned, or appointed offices. By toggling the buttons, presidential interconnects are shown.
The historical information was obtained from general references, primarily from [1].
