This example renders a simple smiley face using React and SVG. A large yellow circle with a black stroke forms the head, while two smaller black circles positioned at the upper left and right serve as eyes. The code uses React 16.13.1 with ReactDOM to manage the DOM, though the SVG markup is written directly in the HTML file rather than as JSX. The face is static, with no mouth or interactive behavior, and outputs at 960 by 500 pixels.
