This example demonstrates a minimal React application that uses D3's `csv` utility to fetch a dataset of CSS named colors from a remote URL. The React component manages the data with a `useState` hook and a `useEffect` hook, displaying a summary message once the data is loaded. The message counts the data's size in kilobytes, the number of rows, and the number of columns using `d3.csvFormat`. While the data loads, the interface shows "Loading..." in a large `<pre>` element. The visualization highlights the integration of D3's data-loading and formatting functions within a React state-driven workflow.
