Cholera map in 3d

Almost every conversation about public health and mapping includes a reference to John Snow's famous cholera map. (Not that John Snow) And generally the sites and slides and posters all use a similar reproduction of the original map. But I was pleasantly surprised when I discovered one group that produced a 3-d version of the map, and did it in a way that made the visualization meaningful.
