d3.geoChamberlinAfrica() The Chamberlin projection for Africa using points [0°, 22°], [45°, 22°], [22.5°, -22°].

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

d3.stackOffsetSilhouette(series, order) Shifts the baseline down such that the center of the streamgraph is always at zero.

node.each(function) Invokes the specified function for node and each descendant in breadth-first order, such that a given node is only visited if all nodes of lesser depth have already been visited, as well as all preceeding nodes of the same depth. The specified function is passed the current node.

d3.geoInterruptedSinusoidal() An interrupted sinusoidal projection with asymmetrical lobe boundaries that emphasize land masses over oceans, after the Swedish Nordisk Världs Atlas as reproduced by C.A. Furuti.

d3.geoStereographic() d3.geoStereographicRaw The stereographic projection.
