This example shows a static smiley face drawn with two eyes and a yellow circular head on a black-outlined SVG canvas. It demonstrates how React can be embedded in a plain HTML page using the React UMD build from unpkg, with the script logging the React object via `console.log(React)`. The SVG elements are hardcoded directly in the markup, not generated dynamically, and the styling uses minimal CSS to remove margins and hide overflow. The code renders a simple smiley face without interactive behavior or data-driven updates.
