This example renders a smiley face as a static SVG graphic using React and ReactDOM. The code defines constants for dimensions, eye offsets, and radius, then composes three `<circle>` elements—one large yellow face with a black stroke, and two smaller black circles for eyes—within an SVG canvas. It uses React's JSX syntax to declare the SVG markup and ReactDOM's `render` method to inject the component into the page's `root` element. The face is drawn from computed center coordinates, with no interactive or animated behavior.
