This example displays a simple, static smiley face constructed from basic geometric shapes. Rendered as an SVG graphic, a yellow circle forms the head, with two smaller black circles for eyes and a dark arc for the mouth, all centered on a 960 by 500 pixel canvas. The visualization is built using React, with the drawing logic relying on D3 v7’s `arc` function to compute the path for the mouth. The circle and eye radii, along with their positions relative to the center, are defined through straightforward arithmetic variables, and the final composition is created using ReactDOM.
