{"version":"1.0","type":"rich","title":"Gradient","description":"This example demonstrates an animated gradient landscape using D3 version 6 and SVG. It shows a sky backdrop with a radial gradient, a sun that moves vertically, and two layered terrain paths with linear gradients. The gradients transition colors over time using SVG `<animate>` elements, while the sun’s position animates via its `cy` attribute. The code uses D3’s `select` function to render static text, and the visual is purely SVG-based with no external data sources.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c16dcc8af576486881b6d9ce6b3c87ec?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
