Smiley Face Part-1
This visualization shows the initial stage of constructing a smiley face using SVG shapes: a yellow circle for the head and two black circles for the eyes, all rendered on a 960×500 canvas. The code employs React 18.2.0 via UMD builds, with ReactDOM rendering an `App` component that outputs a simple "Hello JSX" heading into the root div. The face elements are drawn directly in HTML using SVG circle elements with explicit coordinates, fill colors, and stroke properties, while CSS manages the page layout by removing margins and hiding overflow.
