d3.geoCraig() d3.geoCraigRaw(phi) The Craig retroazimuthal projection. Note: this projection tends to fold over itself if the standard parallel is non-zero; we have not yet implemented the necessary advanced clipping to avoid overlap.

d3.geoCylindricalEqualArea() d3.geoCylindricalEqualAreaRaw(phi0) The cylindrical equal-area projection. Depending on the chosen parallel, this projection is also known as the Lambert cylindrical equal-area (0°), Gall–Peters (45°), Hobo–Dyer (37.5°), and Tobler world-in-a-square (~55.654°).

d3.geoConicEqualArea() d3.geoConicEqualAreaRaw(phi0, phi1) The Albers’ equal-area conic projection. See also conic.parallels.

d3.geoConicEquidistant() d3.geoConicEquidistantRaw The conic equidistant projection; see d3-geo.

d3.geoConicEqualArea() d3.geoConicEqualAreaRaw Alber’s conic equal-area projection; see d3-geo.

d3.geoConicEquidistant() d3.geoConicEquidistantRaw(phi0, phi1) The conic equidistant projection. See also conic.parallels.

d3.geoConicConformal() d3.geoConicConformalRaw(phi0, phi1) The conic conformal projection. The parallels default to [30°, 30°] resulting in flat top. See also conic.parallels.

d3.geoConicConformal() d3.geoConicConformalRaw The Lambert conformal conic projection; see d3-geo.

d3.geoCollignon() d3.geoCollignonRaw The Collignon equal-area pseudocylindrical projection. This projection is used in the polar areas of the HEALPix projection.

d3.geoCircle() Returns a new circle generator.
