A face built from basic SVG shapes—a yellow circle for the head, circles for eyes, and an arc-generated path for the mouth—is centered on a 960×500 canvas. The code uses D3.js v5’s `select` and `arc` APIs to append and position elements, with `transition()` animating the eyebrows up and down over two-second intervals. The rendering is entirely SVG, with all coordinates computed relative to the svg’s center using its width and height attributes.
