This example demonstrates data loading with React and D3, displaying a text summary of a CSV file’s size, row count, and column count. The `csv` function from D3 v5 fetches the remote dataset, while React’s `useState` and `useEffect` hooks manage the asynchronous state update. The resulting message is rendered in a large `<pre>` element, formatting the file size in kilobytes using `d3.csvFormat` to measure string length. The visualization focuses on the interplay between D3’s data utilities and React’s state-driven rendering.
