What country has the best education? Health? Quality of life? Thomas Klepl and Adam Clarkson of Newsweek take a look at important metrics for the world's best countries. It's basically a parallel coordinates plot turned on its side. Each represents a metric, and each circle in a row is a country.
Select a country from the list on the left or by directly interacting with the plot. If a country is top in all categories, like Finland, then all of the scores are going to be on the right. Burkina Faso, on the other hand, is all the way to the left. Of course, this is only the "top" 100 countries.
You can also filter by geographic regions, income, and population groups.
While I'm not totally sure about the ranking system and methodology, it's an interesting look.
