This interactive SVG depicts a cheerful yellow face composed of simple geometric shapes: a large circle for the head, two smaller circles for eyes, and an arc for the mouth. Built with React and D3 v6, the code leverages ReactDOM to render the SVG and D3’s `arc` API to generate the mouth path with specified inner and outer radii and angle ranges. All coordinates are computed relative to the center, making the face’s layout responsive to the 960x500 viewport.
