This example shows a stylized smiley face composed of SVG shapes, with distinct eyes, eyebrows, nose, mouth, and hair rendered in React. The face is centered within a 960×500 viewport, using a yellow circle for the head and colored arcs for the eyebrows and mouth. The code leverages React for component rendering and D3’s `arc()` generator to create the curved eyebrow and mouth paths, applying rotations and translations via SVG transform attributes. Stroke widths, fill colors, and opacity vary across features, highlighting the mix of D3 geometry helpers with declarative React markup.
