This example shows how to load a CSS named colors dataset asynchronously using D3’s `csv` utility, then store the result in React state to display a summary. It uses React’s `useEffect` and `useState` hooks to trigger and manage the data fetch, while the `message` module computes stats like file size, row count, and column count from the parsed data. The visualization renders a simple text summary in a `<pre>` tag, demonstrating the integration of D3 data-loading with React’s component lifecycle.
