This example renders a simple yellow smiley face using SVG circles defined directly in JSX-like HTML markup within a React application. It demonstrates a bare-bones integration of React with SVG, where the face consists of a large filled circle for the head and two smaller black circles for eyes. The code references the global `React` object via `console.log(React)` but does not use any React components or state. A minimal CSS stylesheet removes body margins and hides overflow, ensuring the graphic fills the viewport.
