This example displays a simple text summary of a CSV dataset loaded from a GitHub gist, showing file size, row count, and column count. Built with React and D3.js v6, the app uses `d3.csv` to fetch and parse the data, then displays the formatted result within a styled `<pre>` element. The interface tracks the mouse cursor with a circle overlay, though the functional interaction is limited to this visual follower. The page relies on the `message` module to compose the summary from the parsed dataset.
