Cartograms

 

 

A cartogram is a presentation of statistical data in geographical distribution on a map. In these maps, some variable is substituted for land area or distance. The map above is an area cartogram. These maps use the size of the population to scale each area in proportion to its population. The map above shows the countries of the world and the size of that country with population used to show size on this map. We can see from this map the most populated countries India and China have a huge scale on this map and a country like Canada that is large in area, barely exist on this map because the population is so low compared to land.
