Smiley face
This example shows a stylized portrait of a face rendered with SVG primitives, constructed from basic geometric shapes like circles, rectangles, and polygons to form features such as eyes, eyebrows, a nose, a mouth, and hair. The code uses React to compose the SVG elements and leverages the `arc` function from the d3 library to generate the curved path for the mouth. The layout is dynamically calculated based on the browser window's dimensions, positioning the face at the center of the viewport. All visual elements are defined with inline attributes for size, color, and position, creating a cohesive, cartoon-like illustration.
