This example demonstrates how to load and summarize a CSV dataset of CSS named colors using React and D3. It displays a brief text summary showing the file size in kilobytes, row count, and column count. The code uses React’s `useState` and `useEffect` hooks to manage asynchronous data loading, with `d3.csv` fetching the remote dataset. React renders the message from the `message.js` utility, which formats the summary using `d3.csvFormat` to calculate data size.
