This example demonstrates a simple smiley face drawn with three SVG circles: a yellow face outline and two black eyes, rendered on a 960 by 500 canvas. The markup is hand-authored in HTML, with React 17 loaded from a CDN and an accompanying `index.js` that logs the React global to the console. The face uses fixed coordinates and stroke widths to position the eyes and face, while the layout comment explains centering calculations. No interactive or animated behavior is shown, only the static SVG presentation.
