This example demonstrates how to load and summarize CSS named colors data using React and D3. It fetches a CSV file via D3’s `csv` utility, stores the result in React state with `useState` and `useEffect`, and displays the dataset’s row count, column count, and file size in kilobytes as plain text. The page uses React 16.9 and D3 v7, rendering text inside a `<pre>` element with SVGs commented out in the HTML.
