This example shows a single simplified face rendered as a yellow circle with a black outline, two gradient-filled eyes, a semi-circular mouth, and a small rectangular nose, all centered in an SVG. The face is composed from modular React components, including `BackgroundCircle`, `Eyes`, `Mouth`, and `FaceContainer`, which assemble the SVG elements. D3’s `arc` generator creates the mouth path, while SVG filters and linear gradients style the shapes. A random value generator varies eye offset, radius, and mouth dimensions, producing subtle variability in each render.
