SmileyFace Part1L
A yellow smiley face is rendered as an SVG graphic, centered within a 960x500 viewport. The face consists of three circles: a large yellow head with a black stroke, and two smaller black circles positioned symmetrically for eyes. The rendering uses React to create the SVG elements, with dimensions and offsets defined as JavaScript constants. The component is mounted into the DOM via `ReactDOM.render`, and the graphic is drawn using standard SVG `circle` elements rather than a charting library.
