This example renders a classic yellow smiley face with custom details, including pink blurred blush ellipses and white eye highlights. Using React components and SVG, it centers a yellow circle with a black stroke, two black eyes, and a mouth drawn as an arc. The code leverages D3’s `arc` generator to create the mouth path, while SVG filters like `feGaussianBlur` apply the blush effect. All shapes are positioned via static coordinates within a responsive SVG canvas, with no interactive or data-driven behavior.
