This example displays summary statistics from a CSV file of CSS named colors. It fetches the remote dataset with D3’s `d3.csv` method, then reports the file size in kilobytes, the total row count, and the number of columns. The output appears as plain text inside a `<pre>` element. A commented-out alternative demonstrates using `fetch` with `d3.csvParse`. The page is built with vanilla HTML, CSS, and JavaScript, loading D3 v6 from a CDN.
