This example displays a yellow smiley face with black-outlined eyes and a curved mouth, centered on a blank SVG canvas. The visualization is built with React components, which import and render reusable shape elements. D3’s `arc` generator creates the mouth path, while the face, eyes, and mouth are separated into distinct component files using ES6 modules and React Fragments. The code uses fixed numeric constants for coordinates and dimensions, with no interactive or animated behavior.
