It would be nice to manipulate the brush rectangle with two finger touches. Currently what happens is that one corner follows one finger.
Might need to wait for version 2 and d3/d3-selection#245

I have a [EDIT] half-working version at https://observablehq.com/d/16d21e1d05af5ee1 using d3.pointers

The implementation below seems to work. It's built on d3-selection@2-rc2:

Note that I changed my development approach and this time did everything on a dev notebook directly. Makes it so much easier (in particular) to continuously test on the tablet and the phone each iteration of the code. Previously each change needed a build-upload-refresh loop which was a waste of time.
