This example displays a plain-text summary of a CSV file’s contents, showing the number of rows, columns, and approximate file size in kilobytes. It fetches a named colors dataset from a GitHub gist, parses it with `d3.csvParse`, and writes the resulting statistics into a large `<pre>` element. The page uses `fetch` and `async/await` to load the data asynchronously, with the output styled via CSS. No visual chart or interactive element is present; the focus is on demonstrating data loading and basic parsing with D3 v7.
