A simple SVG face rendered with React and D3 v6, drawn using circles and an arc path. The blue background circle and black eyes are plain SVG elements, while the mouth uses D3’s `arc()` generator to compute the curved path. The component receives hardcoded dimensions and positions, with the face centered in a 960×500 viewport. React’s `ReactDOM.render()` mounts the app, and the SVG uses a `translate` transform to center the drawing. The code does not load external data; all shapes are defined directly in the component.
