This example renders a partial smiley face in a React-powered SVG canvas. The code uses D3’s `arc` function to draw a thick semi-circular mouth, with two dashed placeholder lines for eyes, all centered on a 960×500 coordinate system. The face is built programmatically using absolute coordinates and transformations, with an empty rectangle overlay. The visualization demonstrates basic geometric composition and D3’s arc path generation within a React component, though the final output is an incomplete facial sketch.
