Data Visualization is a way to represent data using graphics or visuals. The information is communicated to the end user in a schematic form that is both aesthetic and functional at the same time. On first look, the map below seems distorted with many parts of the world missing. This is because this map visually represents the population density of a particular location. The areas that appear white are not habituated by a lot of people, where as other areas that appear jet black have a minimum population of 5 people per square kilometre.
This interactive world map was created by Derek Watkins, a graduate student, who was inspired by William Bunge’s The Continents and Islands of Mankind. Using a slider, a person can easily view the least crowded areas in the world and also the parts that have more than 500 people per kilometre. Each layer of the map is contained in one 23,000 pixel tall spritesheet to reduce load time.
Major parts of Europe and North America still remain less populated per kilometre as compared to the regions of Asia where the population is upwards of 100 people per kilometre. The lower-half of China and the northern-most regions of India has the most people per kilometre in the world.
