The happiness graph displays each countries relative happiness index from http://www.happyplanetindex.org/data/. The happiest countries are represented in purple and the least happy countries are reprsented in white with shades of purple representing everything inbetween. Grey represents countries that are undefined.
The GDP graph displays each countries relative GDP rank from https://www.google.com/fusiontables/DataSource?docid=1N0MaGTWtytF3zW-nj7OGnJFB3lf_n4Zcr54sib4#rows:id=1. The countries with the highest GDP are represented in green and the countries with the lowest GDP are represented in white. Grey represents countries that are undefined.
GDP VS Happiness plots each country's GDP (in $) vs their happiness index. Different regions are represented by different colors as shown by the key. Only the most interesting regions are colored. Central and South America are interesting because they are particularly happy given their GDP. Western Europe is interesting because it is particularly unhappy given the GDP.
There is clearly a correlation between how wealthy a country is and how happy it is. But as seen in the graph above, there are some countries, (and perhaps even entire regions!) where people are happier than other countries with the same money.
How are these countries happier relative to their wealth?
Are they perhaps simply relying on drugs?
