This interactive smiley face visualization uses React to render a cartoon-like face composed of layered SVG shapes, including circles for the eyes, an arc-based mouth, and elliptical ears. The face is drawn using D3’s `arc()` generator for the mouth and eye/ear paths, while custom line elements create subtle facial details. The rendering relies on React 17, D3 v7, and SVG transforms to position each component around a central coordinate system. The design demonstrates how D3 geometry helpers can be combined with React’s declarative JSX markup to construct a playful, static illustration without external data.
