A stylized smiley face rendered with React and D3 v6, centered within an SVG canvas. The face uses a yellow circle for the head, two black circles for eyes, and an arc-generated mouth. The mouth is drawn using D3's `arc()` generator, with inner and outer radii and angular extents defined in the code. The SVG elements are positioned via a translated `<g>` group, and styling is applied through inline attributes like `stroke-width`.
