This example shows a stylized smiley face rendered as an SVG graphic, with yellow circular head, two elliptical ears, white eyes with black outlines, a red elliptical nose, a black arc mouth, and a thick black line representing a cigarette. The visualization is built using React and D3 v7, with the `arc()` generator from D3 computing the mouth’s curved path. Fixed constants define all dimensions and positions, while React’s JSX structures the SVG elements. The drawing is centered via a `translate` transform, and the code uses ReactDOM to mount the component into the page’s root div.
