This visualization demonstrates a minimal React and D3 integration for loading and summarizing a CSS Named Colors dataset. The app uses React’s `useState` and `useEffect` hooks to manage asynchronous data fetching, while `d3.csv` retrieves the CSV file from a GitHub gist. Once loaded, the `message` function computes and displays the dataset’s file size, row count, and column count using `d3.csvFormat` and string concatenation, rendering the result inside a `<pre>` element. Before data arrives, the UI shows a simple “loading...” placeholder.
