Cylindrical projections
=========================================================================================
Cylindrical projections project the sphere onto a containing cylinder, and then unroll the cylinder onto the plane. Pseudocylindrical projections are a generalization of cylindrical projections.
geoEquirectangular()
Source · The equirectangular (plate carrée) projection.
geoMercator()
Source · The spherical Mercator projection. Defines a default projection.clipExtent such that the world is projected to a square, clipped to approximately ±85° latitude.
geoTransverseMercator()
Source · The transverse spherical Mercator projection. Defines a default projection.clipExtent such that the world is projected to a square, clipped to approximately ±85° latitude.
geoEqualEarth()
Source · The Equal Earth projection, an equal-area projection, by Bojan Šavrič et al., 2018.
geoNaturalEarth1()
Source · The Natural Earth projection is a pseudocylindrical projection designed by Tom Patterson. It is neither conformal nor equal-area, but appealing to the eye for small-scale maps of the whole world.
