A yellow smiley face with black outline, two eyes, and a green iris in each eye fills the SVG canvas. The face’s mouth is rendered as a thick arc spanning the lower half of the face. The visualization uses React to define the SVG elements and D3’s `arc` API to generate the mouth path. The drawing is static, with all coordinates and radii hard-coded in the React component. The SVG is rendered directly with `ReactDOM.render`.
