What is the unit of width and height ?

[trya2l]

Hi all,

D2 grid diagrams documentation introduces width and height: https://d2lang.com/tour/grid-diagrams/#width-and-height

However it is not that talkative about the options provided and the actual nature of the parameter.

I mean, is 400 in px ? Do people generally just choose any value that goes with them ?

Is there any plan/discussion to add other layout management methods like fractions in typst ?
