Smiley Face
This example renders a simple smiley face on an otherwise empty HTML page. The visualization uses an empty `<body>` element with no JavaScript or external libraries, so the face is shown as a static drawing. It demonstrates the minimal structure of an HTML document, relying solely on the browser’s default rendering. The page contains only the title and a blank body, showing no data or interactive behavior. The work highlights the bare-bones foundation of a web-based visualization, with no D3, Canvas, or other APIs involved.
