A React application renders the CSS named colors dataset, loading it via D3’s `csv` utility into React state with `useState` and `useEffect`. The data appears as a vertical stack of thin horizontal bars, each colored by its RGB hex value from the CSV. While loading, a large “Loading…” message displays. The code uses `ReactDOM.render`, `map` over the data array, and inline styles for background colors, with D3’s `csv` handling the remote file parsing.
