Fork of Smiley Face Part III
This fork of Smiley Face Part III draws a stylized face as an SVG using React and D3. It renders a red circle for the head, two black eyes, a horizontal line for a nose, and a curved mouth path created with D3’s `arc()` generator. The code uses React components to structure the SVG elements and D3 v5 to compute the mouth’s arc geometry. Eye positions and radii are defined as constants, while the head’s size derives from the viewport height.
