This example shows a static yellow smiley face made of three SVG circles with a black outline and two dark eye circles. It demonstrates basic React setup alongside raw SVG markup, where the circles are drawn directly in the HTML. The code includes React and ReactDOM from CDN, but the visible visualization does not rely on React rendering; instead, it uses plain SVG circle elements with fixed coordinates and stroke properties. The index.js merely renders a simple "Hello JSX" heading, leaving the smiley face as the primary visual output.
