A yellow circular face with black eyes and a half-circle mouth is rendered in SVG. Using React to structure the markup and d3.arc to generate the mouth’s path, the visualization draws two offset eye circles and a central smile arc within a fixed 1000×500 viewport. The code applies d3 v6’s arc generator with specific inner and outer radii and angle ranges, while React 16.9 manages the component lifecycle. All shapes are static, with no interaction or animation.
