A red ellipse and a yellow ellipse, rotated 90 degrees relative to each other, are repeatedly rendered at the center of an SVG canvas. The React component `Ellipse` defines the shapes using SVG `ellipse` elements with fixed radii and a black stroke. The `App` component maps over a static array to layer these identical pairs multiple times, creating a dense, overlapping floral pattern. The code uses React 16.10.0 and ReactDOM to render the static visualization.
