Four magenta ellipses are drawn on a light background. Two ellipses have a horizontal orientation with a radius of 15 on the x-axis and 45 on the y-axis, while the other two are rotated 90 degrees, swapping those radii. One pair is centered at the middle of the SVG canvas, and the other pair is translated downward by twice the vertical radius. The React component `Ellipse` renders SVG `<ellipse>` elements with explicit `cx`, `cy`, `rx`, and `ry` properties, using a black stroke and magenta fill with default opacity.
