This example shows the distribution of CSS named colors by plotting each color’s keyword against its RGB hex value as a computed field, using a semi-transparent area mark with tooltips for individual names. It loads color data from a CSV via d3.csv, then renders the visualization through the Vega-Lite API, which registers Vega and Vega-Lite instances and configures an SVG view with a custom tooltip handler. The chart auto-fits to the window size and applies a dark themed configuration for labels and axes.
