This example presents a grid of fifteen procedurally generated cartoon faces, rendered as yellow SVG circles with black outlines, eyes, and arced mouths. Built with React for component composition and D3 v7 for the `arc` generator in the mouth, each face varies randomly in eye offset, radius, and mouth dimensions. The code reads properties like `centerX`, `centerY`, and `strokeWidth` to position a shared `FaceContainer` SVG wrapper, producing a playful, varied collection of expressions.
