This example shows the CSS named colors dataset loaded asynchronously and rendered as colored bars, with a loading message displayed until the data arrives. The code uses React hooks (`useState`, `useEffect`) to manage data state and trigger the D3 `csv` utility to fetch the remote CSV file. Once loaded, each row is mapped to a `<div>` whose background color is set from the color value, demonstrating a simple integration of React’s declarative rendering with D3’s data-loading API.
