This example demonstrates asynchronous data loading in a React component using D3’s `csv` function to fetch a named-color dataset from a GitHub gist. The app renders a text summary displaying the data size in kilobytes, row count, and column count once the CSV arrives, with a loading message before completion. It uses React hooks (`useState`) to manage state and invokes `d3.csv` within the component. The visualization is minimal, showing only a `<pre>` element with dynamic text, originally intended to accompany a "following circle" SVG sketch visible in the HTML comments.
