This example demonstrates loading a CSV dataset from a remote URL using React state and the `useEffect` hook, with D3’s `csv` utility fetching the data asynchronously. While the data loads, the interface displays “Loading...”; once available, a message summarizes the dataset’s size in kilobytes, row count, and column count, computed via `d3.csvFormat`. The visualization itself is minimal—a large preformatted text element—highlighting the integration of D3’s data-loading and formatting APIs within a React component’s lifecycle.
