This example shows a stylized smiley face rendered as an SVG, with a red circular head, asymmetrical elliptical eyes, and a mouth drawn as an arc. The face is centered in a 960 by 500 viewport. The code integrates React for component structure and rendering, while it uses D3’s `arc` generator to compute the mouth path. ReactDOM mounts the component into the DOM, and all shapes are drawn with SVG elements such as `circle`, `ellipse`, and `path`. The visualization relies on fixed numeric parameters for positioning and sizing, with no external data source.
