This example demonstrates a simple animated solar system using SVG primitives. A gradient-filled circle represents the sun, while a smaller gradient-filled planet moves along an elliptical orbit path represented by a dashed grey ellipse. The animation is driven by SVG’s built-in `<animate>` elements, which update the planet’s `cx` and `cy` attributes over a five-second loop. Radial and linear gradients define the celestial bodies’ coloring, and the code directly uses React in the parent application, though this bare HTML file relies purely on native SVG and CSS.
