The smile face example displays a simple yellow circle with two smaller black circles for eyes, rendered as static SVG shapes on a 960x500 canvas. It uses React 18.2.0 through a UMD script tag, though no React components are actually defined. The visualization is built entirely with raw SVG elements—a `<circle>` for the face and two `<circle>` elements for the eyes—each with explicit coordinates for positioning. The code loads React and logs ReactDOM to the console, but relies on pure markup without any dynamic behavior or data binding.
