This example demonstrates loading and parsing CSV data using D3.js version 7. The page displays a message summarizing the dataset’s size in kilobytes, row count, and column count, which is extracted from a CSV file hosted on GitHub Gist. The code calls `d3.csv` to fetch and parse the external data, then uses `d3.csvFormat` to calculate the raw data length. The visualization also includes a decorative SVG illustration (City.svg) embedded in the HTML, with an h1 heading and CSS-styled message container.
