A horizontal stripe chart visualizes all CSS named colors, with each color represented as a thin 4-pixel-tall bar spanning the full width of the container. The example demonstrates combining D3's `csv` loader to fetch a remote dataset of color names and hex values with React's `useState` and `useEffect` hooks to manage asynchronous data loading and render the resulting rows. Once loaded, React maps over the data array, styling each div's `backgroundColor` from the parsed CSV field, creating a continuous gradient-like ribbon of the complete CSS color palette.
