This example demonstrates a React and D3.js integration for asynchronously loading and displaying a CSV dataset. It shows a simple status message indicating whether the data has been successfully fetched or is still loading, using a `pre` element for large text output. The code uses `useState` and `useCallback` hooks from React, and calls the `csv` function from D3 to parse a remote CSS color palette file. The application renders a dynamic message based on the data loading state, showcasing how to combine React’s declarative UI with D3’s data processing capabilities.
