Albers USA

Full Screen

A visual explanation of how D3’s Albers USA composite projection divides the earth into four areas, similar to a k-d tree. This only applies to D3 versions prior to 3.1.8, which rewrote the Albers USA projection to use clipping, offering greater flexibility. (See Albers USA + PR for a related example that preserves Puerto Rico.)
