Eighteen faces appear in a grid, each with a yellow circular head, black outline, two eyes, and a d3.arc-generated mouth. The faces’ parameters—stroke width, eye offset and radius, and mouth dimensions—are randomized per instance, creating subtle variations across the group. Built with React components, the visualization uses D3 v5’s `arc` API to construct the mouth paths and `range` to generate the array of faces. Each face is rendered as an SVG group translated to its center position.
