A yellow circle with a thick black outline and two smaller black circles as eyes forms a simple smiley face. The SVG is drawn directly in HTML using basic `<circle>` elements with attributes for position, radius, fill, and stroke. The code demonstrates a bare minimum HTML page that combines inline CSS to remove default margins and JavaScript-free SVG rendering in a static 960 by 500 viewport. This example serves as a minimal introduction to embedding vector graphics in a web page without additional libraries or frameworks.
