This example shows a cartoon face built from separate React components for the background circle, eyes, and mouth. The face is rendered as an SVG, with the mouth drawn using D3’s `arc` generator to create a semi-circular path. The React components receive numeric parameters for size and position, and the `FaceContainer` centers the drawing within the SVG canvas. The code uses React 16.9, D3 v5, and is part of a video course demonstrating component-based visualization.
