This example shows a grid of eighteen colorful cartoon faces on a pink background, each randomly generated with distinct eye positions, mouth arcs, and stroke thicknesses. The faces are built from React components (`Face`, `Eyes`, `Mouth`, `BackgroundCircle`) that compose SVG shapes, with the `FaceContainer` managing the SVG coordinate system. It uses D3 v5’s `arc` generator to create the mouth paths and `range` to produce the array of faces, while React renders the SVG output to the DOM.
