USA English Dialect Variation Map
The attached Instagram post shows a really cool attempt that Rich Aschmann, a linguist, made as a hobby to map the differences in speech across the United State of America. While likely not a perfect representation of dialects in the USA, as some of the commentors on the post seem to disagree with some of the dialects shown, the map is still very interesting, and is generally good at giving a way to visualized different dialects across the USA.
