A beautiful visualization of languages

I recently found this map on twitter and I couldnt stop looking at it...

Here were some of the interesting things I found

Chinese (and its dialects) is the most spoken language, however its range across regions is really small
Was surprised to see that Marathi, Telegu and Tamil, Bengali (Indian regional languages) are almost as widely spoken as Korean or German or more
I never knew Arabic was spoken in so many different regions
Spanish is spoken in the most number of countries it seems - It is a very useful language to learn globally.

Did anything in this picture surprise or inspire you?
