This example demonstrates how React and D3 can work together to load and summarize a dataset. It fetches a CSV file containing CSS named colors using D3’s `csv` utility, then displays a brief statistical message about the data, including its size in kilobytes, row count, and column count. React’s `useState`, `useEffect`, and `useCallback` hooks manage the asynchronous data loading and state updates. While the page shows “Loading...” initially, the final output is rendered as a large preformatted text block, highlighting the integration of D3’s data parsing with React’s component lifecycle.
