Smile
A yellow smiley face rendered with React and D3 fills the browser window, centered on a responsive SVG canvas. The face consists of a circular head, two eyes, and an arc-based mouth, all drawn as SVG elements. The code uses React components for each facial feature, while D3’s `arc()` generator creates the mouth path. The face is positioned using `translate` transforms, with dimensions computed from the window size to ensure it scales dynamically.
