This example renders a vertical stack of colored horizontal bars representing CSS named colors. The page loads color data from a CSV file using D3’s `csv` utility, then passes the parsed array to React components via `useState` and `useEffect`. Each row’s `RGB hex value` becomes the `backgroundColor` of a full-width `<div>` strip. While the data loads, React displays a “Loading…” message in a `<pre>` element. The visualization demonstrates a minimal React-D3 integration, where D3 handles data fetching and React handles the DOM rendering.
