Eighteen identical smiley faces, repeated in a grid, are rendered using React components and D3’s `arc` generator for the mouth. Each face draws a yellow background circle with a black stroke, two offset eyes, and an arc-based smile, all assembled via `FaceContainer` that applies a center translation. The visualization demonstrates component reuse with fixed props, using React-DOM for rendering into an SVG, while D3 v5 provides the `range` helper for the grid and trigonometrically computed arc paths.
