Is this just a case of not wanting to set a scale as a percentage, but instead a certain width?

Because it seems this "auto scaling" is just a hardcoded 750px width.

Yeah, I'm not entirely how the computation works, it's computed using the actual width of the window and a maxWidth of 750 for the zoom-out area.

I would be fine removing it and setting a percentage but I don't have too much context here.

My point is: does it make sense to have a % API? Are we using that as third party somewhere? Would a width work there instead?

Ah good point, Well, in my mind, the zoom level becomes kind of like a range picker (see the storybook), in which case the % API seems better no?

I always saw the state as representing a percentage of zoom 👍

Any way we can make this auto scaled private? Maybe a symbol?
