Huh, took me a while to figure out where these numbers came from... surprised I had never noticed this before but it seems weird that offset sets the left edge of each bar rather than its center. Oh well, a little late to change that. Why does the second one get 3.099 instead of 3.1?

I'm not sure.
With a regular array, we get:
[0.5, 1.7999999999999998, 3.1]
with a typed array, we get:
[0.5000000014901161, 1.8000000059604644, 3.099999988079071]

ah ok, that's just because it's a Float32Array ie single precision, not double. But it's still closer to 3.1 than to 3.099 😏
