This example renders a simple cartoon face using React components and SVG. The Face component composes background circles for the head, offset circles for eyes, and an arc-based mouth. The mouth shape is generated with the D3 `arc` generator, producing a curved path. The SVG canvas is created via React’s JSX markup, with coordinates centered through a translation transform. The code uses d3.v7’s arc API and React 16.9 for structure, drawing a static, yellow-faced character without animation or data input.
