This animated SVG landscape mimics a Bob Ross painting, showing a mountain scene with a sun that rises and sets over a gradient sky and ocean. The image cycles through a day-night transition over 20 seconds, altering sun position, opacity, and the colors of the sky, mountains, and water. The visualization uses raw SVG elements, including `rect`, `circle`, and `path`, combined with SMIL animations within `<linearGradient>` definitions to create the shifting atmospheric effects.
