This example renders the full set of CSS named colors as a vertical stack of horizontal bars, each colored according to its hexadecimal value. The visualization uses React 18 with functional components and hooks (`useState`, `useEffect`) to manage asynchronous data loading, while D3’s `csv` utility fetches the color dataset from a GitHub gist. Once loaded, React maps each row to a styled `div`, setting the background color from the `Hex rgb` field. The visualization demonstrates how D3 can handle data acquisition and parsing while React manages the DOM rendering.
