A yellow smiley face rendered with SVG, centered on a 960×500 canvas. It shows a yellow circle for the head, two black eye circles, and a mouth drawn as an arc, all created with React and D3 v6. The code uses D3's `arc` generator to define the mouth path, and React constructs the SVG elements with attributes like `cx`, `cy`, `r`, and `stroke-width`. The face is positioned using a `translate` transform based on the canvas center.
