This example shows a classic smiley face constructed from layered SVG shapes, centered within a yellow circular background with a black outline. The face includes two black eyes and a curved mouth arc, all positioned using absolute coordinates relative to the center of the viewport. The visualization is built with React components that render individual SVG elements—a background circle, eyes, and a mouth—using D3’s `arc` generator to define the mouth’s path. The entire composition is rendered as an SVG graphic with a static, fixed layout and no interactive behavior.
