It's a map of the tiny proportion of people that are actively trying to learn a new language.

And it's aspirational -- people are learning the language of the places they want to long-term visit or live. So those Nordic people want to go somewhere *warm*.

The #Netherlands certainly teaches English well -- 90% of the #Dutch are fluent. I suspect that if you could see language #2 it would also be Spanish.
