A stylized face built from SVG shapes, rendered as a yellow circle with black outline, two eyes, and a mouth arc. The geometry is computed relative to the center of a 960×500 viewport using React for component structure and the D3 arc generator for the mouth path. Eye positions and radii are defined as constants, while the mouth uses inner and outer radii with a defined start and end angle. The visualization demonstrates combining React’s declarative JSX with D3’s functional shape APIs for a simple custom chart.
