This example displays the metadata of the most browsed songs in 2021, including file size, row count, and column count, on a page with a decorative background. It loads a CSV dataset using `d3.csv` and computes the message text with `d3.csvFormat` and `Math.round`. The page uses D3 v7, vanilla JavaScript, and CSS to present the information, with the result inserted into a `<pre>` element via `textContent`.
