A static face is drawn with SVG circles for eyes and a d3.arc path for the mouth, centered within a 960×500 viewport. The React component structure separates the face into BackgroundCircle, Eyes, and Mouth subcomponents, with the FaceContainer applying a transform to position the group. The example demonstrates the use of d3.arc to generate the mouth curve and React’s component composition to assemble a simple visual element, though no interactive mouse-following behavior is visible in the provided code.
