An array of arrays of hexadecimal color strings from the “PuOr” diverging color scheme. The kth element of this array contains
the color scheme of size k; for example, d3.schemePuOr[9] contains an array of nine strings representing the nine colors of the
purple-orange diverging color scheme. Diverging color schemes support a size k ranging from 3 to 11.
