Edit 1: I've updated the map and the data. The latest data avaliable is by Ethnologue and is as of 2019.
As per standards, I've removed dialects entirely, especially affecting Hindi (after much research on the Hindi Belt and languages/dialects such as Bhojpuri and Magahi). I have also replaced a small number of Ethnologue's estimations with figures from the languages' specific Wikipedia pages, if the former estimation was influenced by the splitting of dialects.
I've resized all of the circles, as well as redrawn the map to define the continental borders between Asia and other continents.
Thank you everyone for playing!
