This example demonstrates how to load and parse a CSV dataset using D3.js version 7. The page displays a header message and a pre-formatted text block that counts the data's size in kilobytes, number of rows, and number of columns. The visualization uses the `d3.csv` API to fetch a remote CSV file from a GitHub gist, then processes the parsed data to calculate and present these summary statistics. The page also embeds an external SVG image depicting a virus, and uses minimal CSS styling for typography and background colors.
