This visualization shows a simple smiley face composed of a yellow circle, two eyes, and a curved mouth, rendered as SVG elements centered on a 960 by 500 canvas. The React component uses D3’s `arc` generator to create the mouth path with specified inner and outer radii and angular extents. React 16 renders the SVG structure, while D3 v5 supplies the arc calculation, with all positioning handled through translation and fixed pixel offsets.
