This example displays a yellow smiley face composed of SVG shapes, centered on a 960x500 canvas with a black outlined circular head, two eyes, and a curved mouth. The visualization is built using React and D3, leveraging D3's `arc` function to generate the mouth's path with defined inner and outer radii and angular bounds. The remaining shapes are drawn as standard SVG `circle` elements, with all coordinates and dimensions predefined as constants within the React component.
