This example shows the initial step in constructing a smiley face with SVG shapes, featuring a yellow circle outline with two black eye circles. The code manually positions these shapes using static coordinates within an SVG element, while a React app renders a simple "Hello JSX" heading. It uses React and ReactDOM from UMD builds, with the SVG markup embedded directly in the HTML file rather than generated through React components. The visualization does not yet include the mouth, as indicated by the half-finished face.
