This example shows a static smiley face rendered as a yellow circle with a black outline. It demonstrates fundamental DOM manipulation by using React to create an SVG element. The code defines a simple React component that returns an SVG circle, specifying its center coordinates, radius, fill color, and stroke properties. It uses React 16.9 and ReactDOM to render the component into the HTML document, while the SVG viewport is set to 960 by 500 pixels. No interactive behavior is present in this version.
