This example generates a grid of 18 stylized faces, each built from reusable React components for the background circle, eyes, and mouth. The faces are rendered as SVG elements within a shared coordinate system, using d3’s `arc` generator to draw each mouth. Eye radius varies randomly per face, while all other facial features and positions remain constant. The visualization demonstrates component composition and d3 integration within a React framework, with the SVG output driven by the `FaceContainer` component.
