A static yellow smiley face rendered as raw SVG circles, with a head and two eyes drawn on a 960x500 canvas. The example demonstrates direct SVG markup in an HTML file, alongside a separate React app that mounts a simple "Hello JSK" heading via `ReactDOM.render`. Although React and ReactDOM are loaded, the face itself is not generated by React—it is plain SVG embedded in the document. The code shows a minimal setup for combining declarative React components with hand-written SVG shapes.
