A stylized cartoon face fills the browser window, rendered as a collection of SVG shapes that together depict the character Danny Phantom. The code builds the face using individual React components for circles, rectangles, polylines, and polygons, positioning them via absolute coordinates calculated from the window size. D3’s `arc` function generates the mouth path, while the hair and nose are defined by static point arrays. The example demonstrates how React and D3 can be combined to create a purely vector-based illustration without any underlying data.
