This example builds a stylized face from reusable React components, layering a gradient background circle, ellipses for eyes, and a mouth arc into an SVG canvas. The face is centered using a FaceContainer that applies a translation, while D3’s `arc()` generator defines the mouth and tooth shapes. Teeth are rendered as white arcs with black dividing lines, and a linearGradient fills the background. The code uses d3.v7 and React 18, with all coordinates and dimensions passed as props to control facial feature placement.
