This example visualizes CSS named colors as a radial burst of arcs arranged in a pie chart, with each arc filled using its corresponding color’s hex value from a CSV file loaded via D3’s `csv` utility. React manages the component state and renders the SVG paths, while D3’s `pie` and `arc` functions compute the angular layout and arc geometry. The data loads asynchronously with `useEffect` and `useState`, and the visualization updates once the CSV is fetched.
