Fork of Smiley Face Part II
This fork of the Smiley Face Part II example creates a responsive, full-window SVG smiley face using React. The code defines the face through geometric primitives—concentric circles for the head, eyes, and mouth—with dimensions computed from the browser window’s width and height to center the composition. It uses React’s `ReactDOM.render` to inject the SVG into the page, with styling for the yellow fill and black stroke set via SVG attributes. The implementation relies on React 16.9.0 from the UMD distribution, rendering entirely through declarative JSX rather than imperative drawing commands.
