smiley
This visualization displays a classic smiley face constructed from basic geometric shapes, with a yellow circle for the head, black-outlined white eyes, and a curved mouth arc. Built using React and D3 v6, it leverages D3’s `arc()` generator to create the mouth path from inner and outer radii and start/end angles. The SVG rendering uses React components for circles and paths, with transforms positioning elements relative to the center of a 960x500 viewport.
