This example demonstrates how to integrate React with D3 for data loading and display. It fetches a CSV file containing CSS named colors using D3’s `csv` utility, then stores the result in React state via the `useEffect` hook. After loading, the app renders a text summary using the `message` module, which reports the formatted data size in kilobytes, row count, and column count. The visualization uses React’s `useState` and `useCallback` hooks alongside D3’s `csvFormat` to present a minimal, text-based output.
