This example shows the complete set of CSS named colors as a radial burst of pie slices, with each slice filled by its corresponding RGB hex value. The visualization uses D3’s `csv` loader to fetch color data, `pie` and `arc` generators to compute slice geometry, and React to render the SVG paths. The chart is centered with a fixed width and height, and a loading state appears while data is fetched. The code demonstrates combining D3’s data manipulation with React’s declarative component rendering.
