A 'ggplot2' Extension to Visualize Two Variables per Color
Aesthetic Through Color Space Projections
Description
A 'ggplot2' extension to visualize two
variables through one color aesthetic via mapping to a color space
projection. With this technique for 2-D color mapping, one can create a
bivariate choropleth in R as well as other visualizations with multivariate
color scales. Includes two new scales and a new guide for 'ggplot2'.
