This example demonstrates how to load and summarize a CSV dataset using React and D3. It fetches a CSV file of CSS named colors and displays a concise text summary showing the data size in kilobytes, row count, and column count. The visualization uses React’s `useState` and `useEffect` hooks to manage the loading state, while D3’s `csv` function fetches the remote data and `csvFormat` calculates its size. The interface initially shows “Loading…” until the data arrives, then updates with the computed statistics.
