Hello

Works on my touchscreen Chromebook but not my iPhone; guess because you’re using d3.mouse?

I didn't know you could use a pencil 2 on an iPhone; I only tested it on an iPad.

Oh, I actually just meant using my Galaxy Chromebook Stylus, and my finger, on the Chromebook, works! But touch on iPhone doesn't.

Thanks for clarifying. This notebook was just for me to learn how to read pencil data, it's not a general solution for touch. Also note that it's based on d3@5, and should be upgraded to d3@6, probably including https://observablehq.com/@d3/multitouch
