part 1
This example displays a yellow smiley face with two black eyes on a blank canvas, all rendered as scalable vector graphics. The face is constructed using SVG circles via React, with the D3.js library imported solely for the `arc` function, though the code does not actually use it. The face is centered in a 980 by 500 pixel viewport, with the head, eyes, and stroke width defined by hardcoded numeric constants. The visualization is static, showing no animation or interaction.
