This example shows a half-finished smiley face rendered as a static SVG graphic. The code uses React to define the SVG elements, including a yellow circle for the face, two black circles for the eyes, and an arc path for the mouth. The mouth is created using the `arc` function from D3, which specifies inner and outer radii along with start and end angles in radians. The SVG is positioned using a centered transform, with all coordinates calculated relative to the canvas center. The drawing does not animate or respond to input, presenting only the current geometric state.
