This example uses React and D3 to draw a smiley face as a set of SVG shapes. D3's `arc` generator creates the mouth and ear paths, while React handles the rendering of circles, ellipses, and paths within a single SVG group transformed to the center of the canvas. The face is composed of yellow-stroked ellipses, grey rotated eyebrows, eyes with white pupils, and a nose, all arranged in a fixed 960x500 viewport.
