Making Absinthe Legal?
(I am guessing purely based on US = 'not yet')
Adoption of the metric system in countries? I know France was one of the 1st countries to do so, while US is still in the dark ages.
I don't get why some of the coastlines are black though. I think that's just because of some flaw in the rendering, right?
Congratulations to Nikhil! The answer is indeed the world ordered by the adoption (or not) of the now ubiquitous metric system.
The system was created in France, spread through continental Europe in the 19th century and the far east in the early 20th century. The newly decolonised states adopted it in mid-century and even the UK did towards the turn of the millenium. As Nikhil points out, the US is one of the few now left "in the dark ages".
Thank you to Ankur too for trying!
