This example shows a yellow smiley face drawn with SVG shapes, including a circular head, two eyes, and a mouth arc. The code combines React for component structure and D3’s `arc` generator to create the mouth path. The face is centered using a `g` transform, with fixed pixel dimensions for the SVG canvas, eye offsets, and stroke width. The project uses React 16.9, ReactDOM 17.0.2, and D3 v6, rendering the final graphic to the DOM.
