This example demonstrates how to load and parse CSV data with D3.js, displaying the dataset's size, row count, and column count on an HTML page. The visualization pairs a static SVG city illustration with a styled message area that updates dynamically. The code uses `d3.csv` to fetch the remote CSV file, `d3.csvFormat` to calculate the data size in kilobytes, and JavaScript to populate the message container. The page also incorporates CSS for typography and layout, with D3 v7 loaded via a CDN.
