Most of the North American indigenous languages have less than 500,000 speakers; there are a couple exceptions like Aymara which is on there, and it looks like there’re a few exceptions to the “nothing under 500k” speakers rule, I suppose out of curiosity? But yeah there are millions of languages that didn’t make the cut. American historical linguistics also doesn’t seem to be an area of research that’s had much success as far as cohesive theories or visibility, and as it happens colonial genocide tends to destroy native cultures, so it’s disappointing but not surprising that it’s hard to find evidence.
There are hundreds of languages missing from this graphic, likely because it wouldn’t be feasible to include them all
