This example demonstrates how D3 parses a remote CSV file and summarizes its contents. The page displays three statistics about the data: its approximate size in kilobytes, its row count, and its column count. The code uses `d3.csv()` to fetch and parse the dataset from a GitHub Gist, then `d3.csvFormat()` calculates the formatted string length. The resulting message is rendered inside a `<pre>` element with large font styling. The implementation relies solely on D3 v7 and native JavaScript promises, with commented alternatives using `fetch` and `async/await`.
