This example visualizes CSS named colors as a radial burst of pie slices, each slice filled with its corresponding color. It loads color data from a CSV file using `d3.csv`, then renders the chart as an SVG with React. The code uses `d3.pie` to compute arc angles and `d3.arc` to generate the path geometries, with React managing the component state and DOM updates. The dataset includes color names and hex values from the provided gist.
