This example displays a single yellow smiley face drawn as a basic SVG circle centered on a 960 by 500 canvas. The face uses a fixed radius and a black stroke with a defined width, leaving the interior filled with yellow. The visualization is built with React 18, using JSX to declare the SVG `<circle>` element, and is rendered into the DOM via `ReactDOM.render`. The code defines constants for the center coordinates and stroke width to position the shape.
