This example displays a text summary of a loaded dataset, showing the number of rows, columns, and file size in kilobytes. The program uses React's `useState` and `useEffect` hooks to manage data loading asynchronously, fetching a CSV of CSS named colors from a GitHub gist via D3's `d3.csv` utility. The resulting message is rendered inside a `<pre>` element, with the D3 `csvFormat` function calculating the byte size. While the page is styled globally, the core visualization is purely textual, contrasting with the commented-out SVG circle markup in the HTML.
