This example shows a simple smiley face rendered as a static SVG graphic using plain circles. The yellow face and black eyes are drawn with the SVG `<circle>` element, each with specified `cx`, `cy`, `fill`, `stroke`, and `stroke-width` attributes. It uses no external libraries or data sources, relying solely on declarative SVG markup inside an HTML page styled with CSS to remove margins and hide overflow. The graphic is fixed at a 960×500 viewport.
