A yellow smiley face rendered as a single SVG graphic, with black-stroked eyes, a circular head, and a curved mouth arc. The example uses React to declaratively define the SVG elements and D3’s `arc` generator to compute the mouth path from inner and outer radii and angular start/end values. All coordinates are derived from hardcoded width, height, offsets, and radii, producing a static composition centered in a 960x500 viewport. The code imports only the `arc` function from D3 v6.
