This example renders a grid of eighteen cartoon faces, each composed of reusable React components for the background circle, eyes, and mouth. The visualizations demonstrate compartmentalizing complexity by breaking a face into modular parts within a React and D3 v7 environment. Randomly generated eye and mouth radii provide variation across faces, while a shared SVG face container manages positioning. The code leverages React’s component model, D3’s `arc` generator for mouth paths, and the `range` utility to create the layout.
