This example demonstrates how D3’s `d3.csv` method asynchronously fetches and parses a CSV file from a GitHub Gist, then uses `d3.csvFormat` to convert the parsed data back into text. The page displays a large summary in a `<pre>` element showing the total row count, column count, and approximate data size in kilobytes. The code also includes commented-out manual `fetch` and `d3.csvParse` alternatives, highlighting D3’s built-in parsing pipeline in a minimal HTML document.
