This example displays a green, emoji-like face with a smiling mouth and two eyes, all rendered as SVG shapes on a 960 by 500 canvas. The face’s components are positioned using a centralized group transformation, while the mouth is drawn with a D3 arc. The React app imports the `arc` function from the D3 library to define the mouth’s path, and uses SVG circles with computed offsets for the eyes and face outline. The code is a refactored version that keeps the markup clean and concise.
