Smiley Face 1
A grid of eighteen randomly generated smiley faces, each with a yellow circular head, black stroke, two eyes, and an open mouth, demonstrates parametric variation. The faces are rendered as SVG elements in React, assembled from separate components for the background circle, eyes, mouth, and container, with each attribute like eye offset and mouth radius set randomly. The mouth is drawn using a d3 arc path, and the grid is generated using d3's range function.
