This gallery example renders a smiling face composed of SVG circles and a path, built with React components and ES6 modules. The face includes a yellow background circle, two black eyes, and a mouth drawn using D3’s `arc` generator to create an annular sector. React fragments allow multiple SVG elements to be returned from components, while the app assembles them into a 960x500 viewport. The visualization demonstrates a modular React–D3 integration, with static parameters defining sizes and offsets for each facial feature.
