This example presents a minimal web page that displays metadata about a product sales dataset. The page shows a title and a pre-formatted text block reporting the dataset’s approximate size in kilobytes, the number of rows, and the number of columns. It loads the CSV file from a remote GitHub gist using D3.js’s `d3.csv` function, then strings together the computed metadata into a plain-text message that is injected into the DOM via `document.getElementById`. The page’s background is set using a CSS rule with a remote SVG image.
