This example loads a CSV file of CSS named colors from a GitHub gist and displays basic summary statistics: the file size in kilobytes, the number of rows, and the number of columns. It uses `d3.csv` to fetch and parse the data, then `d3.csvFormat` and `Math.round` to compute the size, writing the results into a `<pre>` element via `textContent`. Alterna-tive commented-out implementations show the same task using `fetch` with `async/await` and `d3.csvParse`.
