Currently being shown at the Third International Conference for E-Social Science is World Mapper – World Mapper is a collaborative project from the University of Sheffield contains 366 unique views of the world.
The image below is indicative of the project detailing population:
India, China and Japan appear large on the map because they have large populations. Panama, Namibia and Guinea-Bissau have small populations so are barely visible on the map.
Population is very weakly related to land area. However, Sudan which is geographically the largest country in Africa, has a smaller population than Nigeria, Egypt, Ethiopia, Democratic Republic of Congo, South Africa and Tanzania.
