This example is a React-based SVG rendering of a smiley face, built as a fork of an earlier visualization. It shows a yellow circular face with two black eyes and a mouth, centered on a full-window canvas. The visualization uses React and ReactDOM to construct and mount the SVG elements, with dimensions derived from `window.innerWidth` and `window.innerHeight`. The face’s features are positioned relative to the center via a `<g>` transform, and the code includes commented-out alternative markup for a static version.
