A stylized smiley face rendered as a collection of overlapping SVG petal and leaf paths, generated with React and D3 v4. The example defines several petal path shapes and a leaf shape, then uses D3’s `arc` API and React to compose them into a decorative face pattern. The code imports `arc` from `d3` and uses JSX to output the SVG elements, with paths transformed and positioned to create the smiley appearance.
