This example demonstrates how to load and display a summary of CSS named color data using React and D3. The visualization renders a plain-text message showing the dataset’s size in kilobytes, row count, and column count. Data is fetched asynchronously with D3’s `csv` method, while React’s `useState` and `useEffect` hooks manage the loading state and prevent infinite re-fetching. The final output is presented inside a `<pre>` element, initially displaying “Loading...” until the data arrives.
