This example renders the CSS named colors as a pie chart using D3.js within a React application. It loads color data from a CSV file containing color names and RGB hex values, then maps each color to a pie slice using the `pie()` and `arc()` functions from D3. The React component uses `useState` and `useEffect` to fetch the data asynchronously, displaying a "Loading..." message until the CSV is ready. The resulting SVG visualization, centered in a 960x500 viewport, displays each named color as a filled path segment.
