This SVG visualization shows a stylized smiley face centered on a 960-by-500 canvas. The face is constructed from a large circle for the head, two smaller circles for eyes with green and purple pupils, and an arc for the mouth. Additional line elements form eyebrows and short hair-like strokes at the top, all rendered with heavy black strokes. Built with React and D3 v7, the code uses the `arc()` API to generate the mouth path and relies on SVG primitives for all shapes, with the entire composition translated to the canvas center via a `transform` group.
