This example displays a text summary of a CSV dataset’s size and structure in a large, full-screen `<pre>` element, updating after the data finishes loading. It uses React hooks (`useState`, `useEffect`) to manage the asynchronous data fetch, while `d3.csv` loads the CSS named color data from a GitHub gist URL. The `Message.js` utility computes the file size in kilobytes, row count, and column count using `d3.csvFormat`, then renders the result with React DOM.
