Add d3.interpolateHsl.
This allows scale interpolation in HSL space. For example:
var fill = d3.scale.linear()
.interpolate(d3.interpolateHsl)
.domain([0, 100])
.range([d3.hsl(180, .5, 1), d3.hsl(180, .5, 0)]);
You could approximate this in previous versions using d3.interpolateString, but
the new interpolation method is slightly faster and also provides backwards-
compatibility for browsers that only understand RGB.
