This example draws a stylized smiley face using SVG primitives within a React component. It shows a yellow circular face with eyebrows, asymmetric eyes (white, black, and green pupils), and a curved mouth path, all centered in a fixed 960×500 viewport. The visualization uses d3.arc to compute the mouth’s shape, with ReactDOM rendering the SVG elements. Thick black strokes define facial features and limbs, while the code relies on d3.v7 and React 17, with no external data source.
