Smiley Face Part II
This visualization shows a stylized smiley face constructed entirely from SVG primitives within a React component. It displays a large circular head with two eyes, inner white highlights, two ears with smaller highlights, a nose, and a mouth, all arranged symmetrically around a central point. The code uses React to render the SVG elements and D3 v7’s `arc()` function to define the nose and mouth paths, which are drawn with precise start and end angles. A `BackgroundCircle` component and multiple hardcoded circle elements compose the face, with no external data source involved.
