A smiley face rendered as a static SVG drawing. The example uses raw SVG elements—three `<circle>` tags—to depict a yellow head with black outline and two black eyes, all centered on a 960-by-500 canvas. The code relies on inline SVG attributes for positioning and styling, with no external libraries or JavaScript. It demonstrates the simplest possible vector graphic: shapes defined directly in markup, with the body styled to hide margins and overflow. No interactions, animations, or data-driven content appear; it serves purely as a static visual exercise.
