A React and D3v5 example renders a smiley face as scalable vector graphics, composed of a pink background circle, two eyes, and an arc-based mouth. The code demonstrates modular component architecture through ES6 imports, with separate files for each facial feature. D3's `arc` generator creates the mouth path, while React Fragments group the eye elements. SVG circles and paths are positioned relative to a central coordinate system using a transform group. The visualization splits reusable React components into individual modules, showing how to integrate D3 calculations with React's declarative rendering for static SVG compositions.
