The Language Olympics is a neat infographic showing the languages spoken on each of the continents.
Once you go to the link, you have to scroll down to get to it. You’ll pass another infographic related to world languages that I personally find rather incomprehensible, but it might just be me.
I’m adding the link to both The Best “Language Maps” and to The Best Sites For Learning About The London 2012 Olympics.
Thanks to Cool Infographics for the tip.
