A grid of ten randomly generated cartoon faces fills the screen, each with a yellow circular head, black-outlined stroke, two eyes, and an arched mouth. Built with React and D3 v7, the example uses d3’s `arc` generator to construct the mouth paths and d3’s `range` to produce the face count. Every face’s dimensions and positions—stroke width, eye offset, eye radius, and mouth size—are randomized on each render, demonstrating reusable SVG components composed within a React hierarchy.
