A half-finished smiley face rendered as static SVG shapes: a yellow circle with a black stroke forms the head, while two unfilled black circles serve as eyes. The code uses React 18.2.0 via a UMD script tag and raw SVG elements, with hard-coded coordinates for each circle. The example demonstrates basic SVG composition and layout, showing the initial steps of building a facial diagram without any interactive or animated behavior. The face remains incomplete, lacking a mouth.
