This example displays a simple static SVG smiley face—a yellow circle with two black eyes—centered on a 960-by-500 canvas. It demonstrates basic React integration by using React 18 and ReactDOM to render a component into a root element, while the visual itself is drawn directly with SVG circle elements. The code mixes HTML markup, SVG attributes, and a minimal React script, with all styling handled by inline attributes and a small CSS rule. It does not show any interactive behavior or data-driven updates, only a fixed illustration.
