This example displays basic metadata about the USA Airport Geographic Info CSV dataset: its approximate file size in kilobytes, the number of rows, and the number of columns. The page loads the data with `d3.csv` from a remote GitHub Gist URL, then uses `d3.csvFormat` to calculate the byte length. Results are rendered as plain text inside a `<pre>` element, with the page styled using a large default font size. No map or chart is drawn, only the dataset summary is shown.
