This example demonstrates how to load external data in a React application using D3 utilities, displaying dataset statistics as text. It fetches a CSV file of CSS named colors with `d3.csv`, then stores the result in React state via the `useState` and `useEffect` hooks. The app shows a summary message computed by `d3.csvFormat`, reporting the file size in kilobytes, row count, and column count. The visualization is minimal, rendering only the statistical text in a large `<pre>` element, with a loading indicator until the data arrives.
