A yellow smiley face rendered as an SVG circle with two smaller circles for eyes, all positioned against a plain background. Built with React and ReactDOM, the component uses hardcoded dimensions and constants for the face radius, eye offsets, and stroke width to compute the layout dynamically. The SVG elements are drawn via React's JSX syntax, with the root element mounted directly into the page's DOM. No interactive or animated behavior is present; the visualization is a static, programmatically generated graphic.
