This example shows a grid of cartoon faces, each with randomized facial features, rendered as SVG elements within a React application. The code uses D3’s `range` function to generate an array of 18 faces, and each face is composed of reusable React components for the background circle, eyes, and mouth. The mouth’s arc is drawn using D3’s `arc` generator with dynamically assigned radius and width values. No external data is loaded; the visualization is purely generated from randomly varied parameters.
