This gallery example displays a grid of smiley faces, each with randomized facial feature sizes and positions. Built with React components and ES6 modules, it renders SVG circles and paths for the face, eyes, and mouth. The code imports the `arc` function from D3 to generate the mouth’s arc path, while React’s `range` from D3 is used to create the array of faces. Each face is wrapped in an SVG container with a translated group, demonstrating reusable component composition and declarative SVG rendering within a React framework.
