This example displays a React-powered interface that reports the size, row count, and column count of a CSV dataset loaded from a remote URL. The application fetches the named CSS colors data using the D3 `csv` function, then renders a formatted text summary via the `message` function. While a commented-out SVG markup defines a static smiley face with yellow circle and eye elements, the active visualization instead uses a `<pre>` element to show the dataset metrics, relying on React’s state management and D3’s formatting utilities.
