This example builds a static smiley-face composition by drawing a yellow face and two eye circles directly in SVG. The code uses React to render a separate “HELLO JSX” heading, while the SVG markup sits alongside it in the HTML. The face is not interactive and only shows the initial sketch stage, as noted in the README. React 17 and ReactDOM render the JSX element, but the SVG itself relies on plain SVG circles and stroke properties.
