Fork of Let's Make a Face Part I
This example displays a grid of eighteen randomly generated smiley faces rendered with React and D3 v7. Each face is composed of reusable React components for the background circle, eyes, and mouth, with randomized eye offsets, radii, and mouth dimensions. The face components are positioned within an SVG using a `<g>` transform, and the mouth is drawn with d3.arc, creating varied expressions across the grid.
