This example renders a cartoon smiley face as an interactive-free SVG composition. It shows a pink circular head with elliptical eyes, white eye highlights, and a brown arc-shaped mouth, all centered within a 960 by 500 viewport. The face is built using React elements for the head and eyes, while D3’s `arc` generator creates the mouth path. Red curved lines, drawn as SVG `path` elements with explicit cubic Bézier commands, serve as eyebrows and are positioned with `transform` translations. The code combines React’s declarative structure with D3’s geometry utilities, rendering entirely through SVG primitives.
