A grid of 20 randomly generated cartoon faces appears, each with a gradient-filled circular background, stylized eyes, a radial-gradient nose, and an arched mouth created using a D3 arc path. The faces vary in stroke width, eye offset, radius, mouth size, and nose dimensions due to randomized props. Built with React and D3 v6, the SVG components animate the background gradient color over a 12-second loop. The example demonstrates reusable React component composition with D3 shape generators for custom data-driven illustrations.
