This visualization shows a simple, stylized smiley face composed of a yellow circle, two black eyes, and a smiling mouth. It is built with React and rendered as SVG, using D3’s `arc` generator to create the mouth path. The face is centered within a 960×500 viewport, with all facial features sized relative to the main circle’s radius. The code demonstrates a modular component approach, separating the face container, circle, eyes, and mouth into distinct React components.
