The chart does not include every country in the world, and who's "included" and "excluded" on the chart makes all the difference. The graph does NOT prove anything. In an attempt to understand graphs like this, it is not unheard of to exclude the most extreme outliers. Exclude CHL, KOR, BGR, and SVK from the graph, and the remaining countries present a muddled mess that does not support this level of certainty.
A more prudent approach by someone with no skin in the game would be to NOT discount these four outliers entirely, but attempt to account for just what it was that made each country so different from all the others. Perhaps we might learn something.
