This example shows a simple smiley face drawn with SVG shapes: a large yellow circle for the head, and two small black circles for the eyes. The page uses plain SVG markup embedded directly in an HTML document, with no JavaScript libraries or data sources. The SVG canvas is sized at 960 by 500 pixels, and the circles are positioned using explicit `cx`, `cy`, and `r` attributes. Styling is applied through inline presentation attributes and a minimal CSS rule that removes the page margin and hides overflow.
