This interactive example renders a simple smiley face as an SVG graphic, constructed using React components and D3.js shape primitives. A yellow circle forms the head, with two smaller black circles for eyes and a D3 arc path defining the mouth’s curved smile. The composition is built by importing the `arc` function from D3, which generates the mouth’s path data based on configured inner and outer radii and angular start and end points. All elements are positioned relative to a central coordinate system using SVG transforms, with React handling the declarative markup and DOM rendering.
