This example displays a message summarizing a remotely loaded CSV dataset, showing the row count, column count, and approximate file size in kilobytes. It uses React hooks (`useState`, `useEffect`) to manage data loading and rendering, while `d3.csv` fetches the spreadsheet from a Google Docs URL. The `message` helper builds the text output using `data.length`, `data.columns`, and `d3.csvFormat` to measure the string length. The visualization is minimal, rendering the summary in a large `<pre>` tag with no chart or graphical encoding.
