This example renders a smiley face as a React component using SVG. It shows a yellow circle with a black stroke for the face, plus two smaller circles for eyes positioned symmetrically around the center. The code defines constants for width, height, center coordinates, eye offsets, and eye radius, then uses ReactDOM to mount the SVG into the DOM. The visualization demonstrates a basic, static composition with React 16.9.0 and inline SVG elements.
