This example loads a CSV file from a remote URL using D3.js v7 and displays a summary of its size, row count, and column count in a styled text block. The page also renders a static smiley face using SVG primitives like circles and a path, with CSS controlling layout and colors. The CSV data is fetched and parsed with `d3.csv`, then formatted with `d3.csvFormat` to calculate its byte size. The visualization demonstrates basic data loading and parsing while combining text output with simple vector graphics in the same document.
