This example displays metadata about a credit card customer dataset, showing the file size in kilobytes, the number of rows, and the number of columns in a preformatted text block. The visualization fetches a remote CSV file using the `d3.csv` API, then calculates and formats the metadata with `Math.round` and `d3.csvFormat`. The page is styled with CSS, including a credit card SVG background image, and uses D3.js v7 within a basic HTML structure. The dataset is linked for reference, and the computed information is presented as plain text in a centered `<pre>` element.
