Hello HTML
This example renders a stylized cartoon face using React and SVG. The face is composed of a yellow background circle, two eyes, and a curved mouth, all positioned relative to a central point. The mouth shape is generated using the `d3.arc` API, while the layout is managed through React components and a reusable `FaceContainer` that applies a translation transform. The visualization demonstrates a modular component-based approach to building SVG graphics with D3's arc generator.
