Fork of Smiley Face Part IV
A grid of fifty identical yellow smiley faces renders in SVG, each face built from React components that compose a circular background, two eyes, and a curved mouth. The visualization uses D3's `arc` generator to construct the mouth path, while React manages the component hierarchy through props for positioning and sizing. D3's `range` utility generates the array of faces mapped into the React application, showing how D3 and React can work together to create repetitive generative art.
