{"version":"1.0","type":"rich","title":"svg gradient animation","description":"A looping animation of a stylized sunrise and sunset over a layered landscape. The scene uses several inline SVG gradients, including a radial gradient for the sky and two linear gradients for the terrain, each with animated `<stop>` color values. A circle representing the sun moves vertically via an SVG `<animate>` element on its `cy` attribute. All animations repeat indefinitely with a 15-second duration, with the code relying solely on native SVG and SMIL APIs, without any external JavaScript libraries.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c2304d4d064742279d88077fdb0a4455?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
