Projection

You can provide a projection function either by passing `projectionFn` or by choosing among some of the projections provided by `d3-geo` by passing a `projectionId` choosing among the ids below.

Azimuthal projections:

• `geoAzimuthalEqualArea`

• `geoAzimuthalEquidistant`

Equal-Earth projections: `geoEqualEarth`

Cylindrical projections

• `geoEquirectangular`

• `geoMercator`

• `geoNaturalEarth1`

You can also pass a precomputed `projection`, useful when you need to share a projection with other components: this won't be affected internally and will be used as given.

If you don't pass `projection`, `projectionFn` or `projectionId`, the default projection is `geoEquirectangular`.

In other words, the order of precedence here is: `projection`, `projectionFn`, `projectionId`, default.
