Human Terrain: Population in 3D

One essay in particular that I loved was Human Terrain: Population in 3D. It depicted population density along the z-axis, thus demonstrating that the cities we think of as metropolitan centers in the US pale in comparison to the megacities in Asia and Africa. In addition, the detailed map depicted population density within the cities themselves, thus showing which cities were densely packed and which had more of an urban sprawl. Of course, the essay allowed the user to explore — a design decision that promoted delight due to its novel ability to "break the fourth wall" between the reader and the journalist.
