Geographic dispersion

Some languages from Autotyp, colored by areal grouping.

The AUTOTYP project offers a freely downloadable CSV file containing genealogical and geographical data on ~2,700 languages. The geographical data include a division of languages into areal groups according to a system of continental and sub-continental linguistic regions, as well as geographic coordinates (latitude and longitude) that roughly approximate "what is generally considered to be the sociolinguistic center of the language," according to the manual.
