This example displays a stylized smiley face rendered as an SVG graphic, featuring a pink circular head, green eyes with pupils, and a black arc-shaped mouth. Built with React and D3 v7, it uses the `d3.arc()` API to generate the mouth path, while positioning all other facial elements—including circles, ellipses, and lines—through hard-coded coordinates. The face is centered within a fixed 900×500 viewport, with facial features arranged symmetrically to create a playful, static illustration.
