This example displays a concise summary of a CSV dataset loaded from a GitHub gist, showing the file size in kilobytes, row count, and column count. Built with React and D3 v6, it uses the `csv` method from D3 to fetch the data and React hooks (`useState`, `useEffect`) to manage the asynchronous loading state. The resulting metrics are rendered as plain text in a large `<pre>` element, while the original smiley face SVG markup remains commented out in the HTML.
