This fork of a smiley face visualization renders a yellow circle with black outline, two eye circles, and a mouth arc using React and SVG. The code computes positions from the window height to center the face vertically, with eye offsets and radii defined as variables. It uses React’s `ReactDOM.render` to inject the SVG into the page, while the height adapts to the browser’s innerHeight. The example demonstrates dynamic sizing, though it omits the mouth shape despite referencing it in comments.
