This example displays metadata summary information about a credit card customer dataset, presenting the file size in kilobytes, row count, and column count prominently on a page featuring a credit card background image. The code uses D3.js version 7’s `d3.csv` to fetch the CSV file from a GitHub gist URL and `d3.csvFormat` to calculate its byte length. The page is styled with CSS, including a background SVG image and centralized headings, with the computed statistics rendered into a `<pre>` element via JavaScript DOM manipulation.
