This is a cool map fitting counties into Africa to show its size. Often we visualize the world based on what we hear or how often we hear things. I recall arguing with a Canadian about if the new Russia (a few years after the breakup of the USSR) was bigger than his Country. People in the United States often think there states are bigger then they really are (at least in the east cost) while the small size of relatively powerful European countries often surprises us. For me India with over 1 billion people just seems much smaller then I think.
Note: The mapper did not sort correctly when listing countries by size putting China 3 and USA 4 in the world rankings. The data on the web page correctly has the USA having a larger area so I am guessing it is an excel sort on the wrong variable.
