A single yellow circle with a black outline forms the base of a smiley face. Two smaller black circles serve as eyes, positioned symmetrically on either side of the face's vertical center. The code uses raw SVG elements—a `<circle>` for the face and two additional `<circle>` elements for the eyes—directly embedded in an HTML document. The fixed 960 by 500 viewport and manual coordinate calculations for the eye positions are visible in the source.
