This example displays a simple, stylized face built from layered SVG shapes: a yellow circle for the head, two light-blue eyes with black pupils, and a red arc for the mouth. The rendering is driven by a React component hierarchy, with each facial feature defined as a separate reusable component. The code uses D3’s `arc` generator to create the mouth’s curved path, while all positioning relies on SVG attributes within a centered group. The face is hardcoded at 600 by 500 pixels with no interactive behavior or external data source.
