This example visualizes CSS named colors as a radial burst of pie slices, with each slice colored by its corresponding RGB hex value. It loads the dataset from a CSV URL using D3’s `csv` utility, then passes the parsed data to React state. React renders the SVG paths, while D3’s `pie` and `arc` generators compute the slice angles and geometry. The code combines React’s `useState` and `useEffect` hooks with D3 utilities, and falls back to a loading message until the data arrives.
