A minimal SVG drawing of a face rendered as two concentric circles for eyes, a red circle for a head, and a mouth arc. Built with React and D3, the page uses a static SVG element for the eyes while constructing the mouth through a D3 arc generator with specified inner and outer radii and angular extents. The code demonstrates a basic integration of React’s `ReactDOM.render` with D3’s `arc` API for creating geometric shapes.
