A smiling face rendered as a pink circle with black-stroked eyes and a mouth, drawn using SVG within a React component. The visualization computes the face geometry with fixed constants for dimensions and offsets, then uses D3’s `arc()` function to generate the mouth path. The code relies on React’s `ReactDOM.render` and D3 v6, with all shapes positioned via an SVG `<g>` transform at the center of the canvas.
