{"version":"1.0","type":"rich","title":"Fork of Fork of Fork of Bird's Landscape - D3.js","description":"This example presents an animated SVG landscape featuring a bird, trees, dogs, stars, and flowers, all rendered programmatically. The scene includes a day-night cycle simulated through animated gradients, a moving truck, and flying birds with flapping wings. Built with D3.js v3 and vanilla JavaScript, the code dynamically creates SVG elements using `document.createElementNS`, applies CSS animations, and uses SMIL animations like `animateTransform` and `animateMotion` for movement. The sky and sun gradients are defined with SVG `radialGradient` and `linearGradient` elements, animating over a 24-second loop.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/cd1d3b653b464462b937586e83811f8a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
