This example displays the full set of CSS named colors as a stacked sequence of horizontal bars, one per color, ordered as they appear in the CSV data. Each bar’s background color is set directly from the `Hex rgb` field. The application uses React’s `useState` and `useEffect` hooks to asynchronously load and store the data via d3’s `csv` utility, rendering a loading message until the promise resolves. The D3 v7 and React 18 libraries are loaded via CDN.
