This example shows a stylized smiley face rendered as an SVG graphic. A yellow circle forms the background, with two black eyes positioned symmetrically and a curved mouth drawn using an arc path. The visualization is built with React components, where each facial feature is a separate component (BackgroundCircle, Eyes, Mouth). D3’s `arc` API generates the mouth’s path, while React renders the SVG elements within a transformed coordinate system centered on the canvas.
