A yellow SVG smiley face with black eyes and eyebrows is drawn on a 960 by 500 canvas. Using D3 v6 selections and the `arc` generator, a mouth is created and shifted into place via a group transform. The eyebrows are rectangles that animate with chained `transition().duration(2000)` calls, moving downward then upward. The face’s features are positioned by computed width, height, and offset constants in a React-based D3 setup.
