This example demonstrates how to load and summarize CSV data using React and D3. It fetches a dataset of CSS named colors from a GitHub gist, then displays a message showing the file size in kilobytes, the number of rows, and the number of columns. The app uses React's `useState` and `useEffect` hooks to manage the data loading, while D3's `csv` function retrieves and parses the remote CSV file. The result is rendered as text within an SVG-ready page, with the data formatted via `d3.csvFormat`.
