Determine the default height when the projection domain is set #2063

Closed mbostock closed 1 day ago

mbostock commented 2 months ago

We currently determine the default height for whole-world projections automatically (for named projections):

It’d be nice to do that if the domain is specified, too. For example:

Plot.plot({
  projection: {
    type: "conic-conformal",
    parallels: [34.3333, 36.1667],
    rotate: [79, 0],
    domain: ncstate
  },
  marks: [
    Plot.geo(ncstate),
    Plot.geo(nccounties, {strokeOpacity: 0.1})
  ]
})
