Fork of Smiley Face Part III
This visualization displays a classic yellow smiley face centered on an SVG canvas, constructed with React and D3.js. It shows a circular face with a thick black stroke, two offset eyes, and a curved mouth arc. The code uses `d3.arc` to generate the mouth’s path, computing angles and radii for the arc shape. React’s declarative syntax defines the SVG elements, while D3 provides the geometric calculations for the arc’s inner and outer radius and start/end angles. The rendering is static, with no animation or interaction visible in the provided source.
