This visualization displays metadata about a credit card customer dataset, reporting the file size, row count, and column count as text on the page. It loads the data from a CSV file hosted on GitHub using `d3.csv`, then formats the raw data with `d3.csvFormat` to calculate its size in kilobytes. The page is built with HTML, CSS, and D3.js v7, and presents the information in a simple `<pre>` element via the DOM API `textContent`.
