This example shows a yellow smiley face rendered as an SVG graphic, centered within a 960 by 500 viewport. The face consists of a large yellow circle with a black outline, two black eye circles, and a mouth drawn as an arc. The visualization is built using React components, with the mouth path generated by D3’s `arc` function, which specifies inner and outer radii and angular start and end points. The drawing relies on SVG circle and path elements, with positions defined relative to the center via a translate transform.
