This example shows a grid of 18 identical cartoon faces, each rendered with a yellow background circle, two eyes, and an arc-shaped mouth, composed using React components. The faces are generated by mapping over an array from `d3.range` and rendering each `Face` component with randomized eye radii. The visualization uses React to structure the SVG elements, while the mouth is drawn with a `d3.arc` path generator. All faces share the same fixed dimensions and coordinate centers, creating a repetitive pattern with slight variations in eye size.
