This example builds a cartoon face from modular React components, showing a yellow circle with two eyes and a curved mouth on a black stroke. The face is assembled from separate SVG elements—BackgroundCircle, Eyes, and Mouth—within a FaceContainer that centers the drawing. The mouth uses D3’s `arc` generator to create a path with specified inner radius, width, and angle range. The code sets fixed dimensions and styling via React props, with all geometry defined in SVG coordinates. The face is rendered statically at 960 by 500 pixels, with no interaction or animation.
