This example demonstrates how to assemble a stylized face from fundamental SVG shapes within a React application, utilizing D3’s arc generator for the mouth. The composition layers a yellow circle with a black stroke as the background, two eye circles, and a D3 `arc` path for the smile within an SVG container. The `FaceContainer` component handles the SVG coordinate system, translating the center point while the `Face` component coordinates the layout and sizing of each facial feature through configurable props.
