The Pudding has created a series of data visualizations illustrating how the concentration of human populations correlates with different urban challenges. The visualizations use 3D blocks to represent population size and are reminiscent of mountains with peaks, descents, and valleys. Planned cities such as Singapore have high peaks, but stay within a confined area. In contrast, cities that are experiencing uncontained growth, such as Kuala Lumpur are less densely populated, but tend to sprawl in multiple directions. In particular, one visualization shows the unplanned growth of Bengaluru, India, which has led to air and water pollution, through a series of thin peaks that represent the dense urban settlements that surround the city.
