This example is the first step toward building a smiley face, displaying only a single large yellow circle with a black outline. Rendered as an SVG element, the circle is positioned at the center of a 960 by 500 pixel canvas. The code uses React 18.2.0 via `ReactDOM.render` to mount the component, with the SVG markup defined directly in JSX. No additional data or interactivity is present, focusing purely on the static geometric shape.
