This example demonstrates a simple data-loading workflow that displays dataset statistics, including file size, row count, and column count, as a large text output. Built with React and D3, it uses the `useState` and `useEffect` hooks to fetch a CSV file from a GitHub gist via D3’s `csv` function. The loaded data is formatted and summarized using `d3.csvFormat` and the `message` utility, while the interface shows a “Loading…” state until the asynchronous request resolves. The visualization integrates React 16.9 and D3 v7 in a single-page app.
