This example renders a yellow smiley face on a black-outlined circle, centered within an SVG canvas. It uses React components to structure the face, with D3 v7’s `arc` function generating the mouth path from specified inner/outer radii and angles. The code explicitly positions two eye circles via offset coordinates and applies a stroke width to the background circle, resulting in a static, modular composition. The rendering is SVG-based, with React managing the component hierarchy and D3 handling the arc geometry.
