A page displays the metadata of a US cities dataset from a linked CSV file, showing its size in kilobytes, row count, and column count in a text element. A custom background SVG image is applied via CSS. The code loads the remote CSV with `d3.csv` and uses `d3.csvFormat` and `d3.csvFormat`’s length to compute the data size, rendering the summary into an HTML `<pre>` block using the Document Object Model.
