A stylized smiley face assembled from SVG shapes appears centered on a wide canvas. The face uses a horizontal linear-gradient fill and contrasting stroke, with khaki-colored details for eyes, mouth, ears, and a triangular nose. Red geometric elements form a cap atop the head. The visualization is built using React and D3.js, utilizing the `d3.arc` function to generate the mouth path and defining custom SVG gradients for the face and accent colors.
