Smiling Face
A smiling face is drawn as an animated SVG graphic, with a circular yellow head, two eyes, and a curved mouth that expands into a smile. The visualization uses React to render SVG elements dynamically, with state-driven animations that update the mouth’s path coordinates over time. The code relies on React’s `useState` and `useEffect` hooks to manage the animation loop, while SVG elements such as `circle`, `ellipse`, and `path` compose the facial features. The rendering appears as a simple, self-contained interactive example built for a web browser.
