Fork of Hello HTML
This example renders a parameterized cartoon face using React components and SVG. The `Face` component composes a yellow background circle, two eyes, and an arc-based mouth, all positioned via a `FaceContainer` that applies a translation transform. The mouth is drawn with d3’s `arc` generator, using inner and outer radii and fixed start/end angles. The code uses React 16, ReactDOM 17, and d3.v7, with the face dimensions and feature offsets passed as props to control the layout.
