This example shows a simple yellow smiley face drawn entirely with SVG primitives on a plain HTML5 page. A single `<svg>` element contains a large yellow circle with a black stroke, and two smaller black circles positioned as eyes; the mouth is omitted. The code uses vanilla HTML and CSS, with the `transform` attribute on a `<g>` group to center the face at coordinates (300,250). No JavaScript libraries are involved, and the rendering relies purely on static SVG markup.
