This example demonstrates how to load and display a summary of CSS named colors data using React and D3. The app fetches a CSV file from a GitHub gist using the `d3.csv` function, then stores the result in React state with the `useState` and `useEffect` hooks. While loading, it displays a simple "Loading..." message, and once the data arrives, it renders the file size, row count, and column count using the imported `message` utility. The visualization highlights the integration of D3’s data-loading capabilities with React’s component-based state management.
