This example demonstrates loading and parsing external CSV data with D3.js, showing basic statistics about the dataset—its size in kilobytes, row count, and column count—displayed as text on a styled web page. The visualization fetches CSV data from a GitHub gist using `d3.csv()`, processes the response with `d3.csvFormat()` to measure data size, and writes results to a `<pre>` element via the DOM API. The page also includes a static SVG image and custom CSS styling for layout and typography.
