This example renders a static smiley face using React 16.9 and ReactDOM 18.3, with three SVG circles drawn directly in the markup. The outer circle is filled yellow with a black stroke, while two smaller unfilled circles form the eyes. Although the index.js file defines an empty App component and calls ReactDOM.render on the root div, the visible output comes entirely from the inline SVG, not from React-rendered elements. The page uses production UMD builds of both React libraries and applies global CSS to remove margins and hide overflow.
