A single large yellow circle with a black outline forms the head of a smiley face, accompanied by two smaller black circles positioned as eyes. The SVG is rendered directly in the browser using inline `<circle>` elements, with attributes for coordinates, radius, fill, and stroke set manually. The example uses no JavaScript libraries, only static SVG markup. The eyes are placed symmetrically around the center, and the design leaves the mouth unfinished, as indicated by the title.
