A simple SVG rendering of a smiling face, drawn with three circles: a large yellow circle for the head and two smaller black circles for the eyes. The face is centered on a 960 by 500 pixel canvas, with the head outlined by a thick black stroke. The example demonstrates basic SVG shape creation, using the `circle` element with explicit `cx`, `cy`, `r`, `fill`, and `stroke` attributes, all defined directly in the HTML markup without any JavaScript libraries.
