This example presents a minimalist animated landscape of rolling hills beneath a glowing sun. It demonstrates the use of raw SVG elements—including `<rect>`, `<circle>`, and `<path>`—to construct the scene. Gradients defined within `<defs>` create the sky and terrain coloring. The animation relies on SMIL `<animate>` tags to cycle the sun's position and smoothly shift gradient stop colors between palettes, suggesting a slow transition from day to night.
