Smiley face part 1
A static smiley face rendered entirely in SVG, with a yellow circular head, black outline, and two black eyes. The example demonstrates how React and ReactDOM can work alongside raw SVG markup, as the HTML file contains both a React entry point and hand-written SVG elements that draw the face. The React `index.js` file renders a simple "Hello JSX" heading, while the SVG shapes are defined separately in the page structure. The visualization serves as a minimalist illustration of combining React's component model with direct SVG drawing.
