This example displays metadata about a credit card customer dataset, including its size in kilobytes, row count, and column count. The page shows a title, a link to the underlying CSV file, and the computed statistics in a large, bold text block. It uses D3 v7’s `d3.csv` and `d3.csvFormat` to fetch the data from a GitHub Gist and calculate the size, while a custom CSS background image of a credit card is applied. The result is presented as raw text, not a visual chart.
