This example demonstrates how to load and display information about a CSV dataset in a React application using D3. It shows the file size, row count, and column count of a named colors dataset fetched from a GitHub gist. The code uses React’s `useState` and `useEffect` hooks to manage asynchronous data loading, while `d3.csv` retrieves and parses the data. A separate `Message` component computes the statistics and formats the output text, which is rendered inside a `<pre>` element.
