This example displays CSS named colors from a CSV file as horizontal color bars using React. The code loads data with D3’s `csv` utility and renders each row as a styled `div` element, with the background color set from the `RGB hex value` field. React’s `useState` and `useEffect` hooks manage asynchronous data fetching, showing a “Loading” message until the data arrives. The visualization demonstrates a simple React-D3 integration for data-driven styling.
