A smiling face is drawn directly on an SVG canvas using basic shapes: a yellow circle with a thick black outline for the head, and two smaller black circles for the eyes. The example demonstrates static SVG markup within an HTML body, without any dynamic data or JavaScript interactivity. The rendering approach relies entirely on inline SVG elements, with the overall layout fixed at 960 by 500 pixels. The code uses no external libraries, and the styling is limited to hiding page margins and overflow.
