Five identical smiley faces render in a row using React components that compose D3-shape primitives. Each face features a star-shaped background generated with `symbol` and `symbolStar`, circular eyes, and an arc-based mouth built with `d3.arc`. The React app maps over an array from `d3.range` to instantiate each `Face` component, which positions all elements via SVG transforms. Colors and dimensions scale proportionally with the fixed width and height, creating a uniform grid of green faces.
