This example renders a stylized Portuguese water dog face using React and SVG. The dog, built from geometric primitives, includes a black head shape, white eyes with brown pupils, a brown nose with black nostrils, and a red tongue inside a white mouth. The code uses React’s `ReactDOM.render` to mount an `<App>` component that generates SVG elements like `<circle>`, `<polygon>`, `<ellipse>`, and `<rect>`, all positioned relative to the screen’s center. The drawing dynamically adapts to the browser’s inner width and height.
