Six identical smiley faces repeat in a grid, each a yellow circle with black stroke, two eyes, and a mouth. The example demonstrates composing SVG shapes from reusable React components, with the D3 library providing the arc generator for the mouth path. Each face is rendered as an independent SVG via the `FaceContainer`, with fixed dimensions and positioned by a simple transform. The grid is generated by iterating over a range of values from D3, creating a uniform, tile-like arrangement of the same facial expression.
