This example demonstrates a D3.js visualization that combines a static SVG illustration with dynamic data loading. It displays a decorative smiley face with ears, a nose, and a hat, rendered using SVG shapes like circles, ellipses, polygons, and paths. The visualization also fetches a CSV file from a remote URL using D3’s `d3.csv` method, then computes and displays basic dataset statistics—such as file size in kilobytes, row count, and column count—in a styled text element. The page uses custom CSS for typography and layout, while the SVG is centered and responsive. The visualization is built with React and D3 v7, rendering entirely via SVG.
