This example shows a static smiley face composed of three SVG circles: a large yellow filled circle with a black outline, and two smaller black circles for eyes. The component is rendered using React and ReactDOM, though the active visualization is created directly in the HTML file with hard-coded SVG attributes rather than through the commented-out React code. The page imports React 16.9.0 from a CDN and renders into a div with the id "root", while a separate SVG element appears in the body.
