So everywhere except for Russia, Ukraine, Belarus and where there’s no data.
Also a bad choice to put no data and no on the same color.
I’m guessing that this just means that there’s at least a single school willing to teach it, it certainly isn’t all of them.
this is simply wrong, probably for all countries besides Greece itself. I never had it in school and I never heard of such a thing.
In Ireland its still theoretically an option (as in there is an end-of-school exam one can take in the subject) however its only available in a tiny handful of schools nowadays.
It was more widespread in the first half of the last century.
That doesn’t mean a whole lot. If one school in the country offers an elective, is the country highlighted? Certainly we didn’t have widespread classes in ancient anything.
