This example displays all named CSS colors as a radial burst of pie slices, each filled with its corresponding color, creating a full circular spectrum. It loads color data from a remote CSV file using D3’s `csv` utility, then uses React state (`useState`, `useEffect`) to fetch and store the data. The visualization is rendered as an SVG, with D3’s `pie` and `arc` functions computing the slice angles and paths, all positioned around a central point.
