HW Tweak Face
A stylized face built from SVG primitives sits at the center of a 960×500 canvas, composed of a yellow circle, two elliptical ears, black-outlined eyes, and a semi-circular mouth generated with d3.arc. The example demonstrates how to declaratively construct and position geometric elements using React’s JSX syntax, with dimensions and offsets defined as constants. D3’s arc generator computes the mouth path, while React handles rendering the SVG group and shapes. The code relies on ReactDOM to mount the component into the page, and d3.v6 for arc generation.
