Contour polygons. Although most often used for encoding data as position, say to map time and temperature to a horizontal and vertical position in a scatterplot, scales can represent virtually any visual encoding, such as color, stroke width, or symbol size. lab(colors[0]). For example, an ordinal scale might map a set of named categories to a set of colors, or determine the horizontal positions of columns in a column chart. call(d3.

This article covers linear scales (scaleLinear), square root scales (scaleSqrt), log scales (scaleLog), sequential scales (scaleSequential), quantized scales (scaleQuantize), quantile scales (scaleQuantile), threshold scales (scaleThreshold), ordinal scales (scaleOrdinal) and band I'm encountering unexpected behavior when using d3. I want to color both of them but when i use category I would assign a class to each object, following some naming convention like "clr-" + objArr[i]. e a root node always have red color and the left child is blue and the right one is green and if only one child is there See pal_d3() for details.
