This example demonstrates how React and D3 work together to load and summarize a CSV dataset of CSS named colors. The visualization displays a text summary showing the file size, number of columns, and row count once the data has been fetched. It uses React’s `useState` and `useEffect` hooks to manage asynchronous data loading, while `d3.csv` retrieves and parses the remote data. The `d3.csvFormat` API calculates the formatted data size, and ReactDOM renders the final message.
