A yellow smiley face rendered as scalable vector graphics appears centered in an SVG canvas, with two black circular eyes positioned symmetrically on either side. The example demonstrates React’s component-based rendering, using the React and ReactDOM production builds to mount an `App` component that declaratively defines three `<circle>` elements. The face’s dimensions, offsets, and stroke widths are set as JavaScript constants, and the SVG output is embedded directly in the DOM via `ReactDOM.render`. No interaction or animation is implemented.
