Worldmapper

Worldmapper is a cool website that has almost 700 maps! Each map is shaped according to the data that it is about, so each map looks distorted according to the subject. You can find maps on population, food, income, births/deaths, education, resources, violence, etc. It’s organized by category for easy browsing! An example below shows use of coal power rates across the globe. You can see how this world map does not quite resemble the normal world map, rather it's resized to fit the data!

This map shows the use of coal for power across the globe. You can see how the U.S. and China are leaders in this, while most of South America does not use coal or uses very little.
