This is a smiling panda face rendered as a single responsive SVG using React, displayed across the full browser window. The panda’s eyes are animated with layered ellipses and circles to create shiny, lively eyeballs with white highlights, while a red tongue sticks out playfully from its mouth. The code uses React’s `ReactDOM.render` to draw primitive shapes—ellipses, circles, rects, and an SVG path—all positioned relative to the viewport center. The face is composed entirely of geometric elements with black strokes, white fills, and a red accent, emphasizing a clean, vector-based illustration style.
