This example displays a stylized yellow face built from SVG circles and an arc, centered on a 960 by 500 canvas. The face features black-outlined eyes, a simple mouth, and a thick black stroke around the head, all rendered using React components. The code uses D3 v7’s `arc` generator to create the mouth path, with geometric constants defining eye offset, radii, and stroke width to position each element. The visualization is drawn with declarative SVG elements inside a React component, demonstrating a straightforward composition of primitive shapes without data binding.
