This example shows a cartoon face built from simple SVG shapes—a yellow circle for the head, two eyes, and a mouth—centered on a canvas. The face's features are parameterized through props, including offsets, radii, and stroke widths. The code uses React with D3 v7 for the mouth, leveraging the D3 shape library's arc generator to create a half-circle path. The SVG is composed from functional components, with the root scene defined in index.js.
