This example displays the complete set of named CSS colors as a vertical stack of thin horizontal strips, with each strip’s background color corresponding to its RGB hex value from the loaded CSV data. A loading message appears until the data arrives. The visualization uses React’s `useState` and `useEffect` hooks to fetch and store the data, and calls `d3.csv` to parse the remote CSV file, then renders each color bar as a styled `<div>` element via `ReactDOM.render`.
