This example analyzes the contents of a flight dataset loaded from a remote CSV file, displaying a summary of its size, row count, and column count. Using D3.js v7, it calls `d3.csv` to parse the data and `d3.csvFormat` to calculate the file size in kilobytes. A simple pre-styled HTML element presents the result. The page also includes two inline SVG images, with a plane graphic moving across a marquee and a static chart centered below, though no interactive visualization or data-driven rendering is performed.
