About this notebook

ggplot2's reference page for diamonds has no examples, so this notebook says only what the page describes and where Giggly stands.

diamonds holds the prices and other attributes of almost 54,000 round cut diamonds: price in US dollars, weight in carats, the quality of the cut, colour from D (best) to J (worst), clarity, length, width and depth in millimetres, the total depth as a percentage of the mean of length and width, and the width of the top relative to the widest point. Giggly has it as Giggly.Datasets.diamonds/0, a keyword list of columns Giggly.Plot.new/2 takes as it is. The cut, colour and clarity are ordered factors, Giggly.Factors with R's levels, so a plot orders them as R does, the cut from Fair to Ideal.
