This example shows a stylized smiley face built with SVG shapes, including a yellow circular head, black-outlined eyes, and a curved mouth arc, with two ear-like arcs positioned on either side. The visualization is rendered using React for component structure and D3’s `arc` generator to define the mouth and ear paths. Coordinates and dimensions are computed from fixed constants, and the SVG is drawn at 960 by 500 pixels with transformations placing elements relative to the center.
