This example draws a yellow cartoon face in SVG, centered within a 960x500 viewport, using D3’s `select` and `arc` functions. The face features black circular eyes, rectangular eyebrows, and a mouth generated from an arc path. An animation demonstrates D3's `transition` method, which moves the eyebrows upward and back down over two two-second intervals. All shapes are built with D3 selections, and the SVG elements are positioned via translation and attribute assignments.
