This example shows a simple smiley face rendered as vector graphics, composed of a yellow circle with a black outline, two dark eyes, and an arc-shaped mouth. The face is centered within an SVG canvas, with its features positioned relative to the center point. The code uses React to construct the SVG elements and the D3.js `arc` API to generate the mouth’s path. The background circle and stroke are defined explicitly, while the eyes are placed using offset coordinates. The rendering approach relies on SVG primitives within a React component, with D3 providing the arc geometry.
