A smiling face rendered in yellow SVG, composed of circles, ellipses, and polylines, is programmatically assembled from React components. The face includes blinking eyes, a mouth that briefly disappears, and animated cigarettes that move across the canvas while smoke puffs fade upward using CSS keyframes. Built with React and D3 v7, the visualization uses D3's arc generator to create a partially closed eyelid, while SVG elements handle the face’s geometry. The data is static, defined through component props and hardcoded coordinates, with animation driven entirely by CSS rather than D3 transitions.
