This example shows a React component that loads a CSV file of CSS named colors using D3’s `csv` utility, then displays a summary message about the dataset. The data resides in React state via the `useState` hook, with `useEffect` triggering the asynchronous fetch on mount. The rendered output shows file size in kilobytes, row count, and column count, computed using `d3.csvFormat` and array properties. While loading, the component displays the text “Loading...”, and the final message is rendered inside a `<pre>` element styled with a large font size.
