This gallery example renders a yellow, black-outlined face built from SVG primitives—a circle for the head, a pair of circles for eyes, and an arc-based mouth. It uses React components (Face.js, Eyes.js, Mouth.js) to compose the figure, with the mouth’s curved path generated by D3’s `arc` API. The example demonstrates how multiple ES6 modules and React’s `Fragment` and `transform` attributes can be combined to structure a simple visualization.
