This gallery example displays a grid of 72 randomly generated cartoon faces, each with a yellow circular head, white eyes with black pupils, and a curved mouth. The faces are rendered as React components using SVG primitives, with each face’s features varying in position, size, and offset based on random values. The code leverages the `d3.arc` API to construct the mouth path, while React maps over an array from `d3.range` to instantiate each face. The visualization demonstrates how randomized parameters can create diverse, expressive compositions within a fixed layout.
