{"version":"1.0","type":"rich","title":"Fork of Double Harmonic Black and white","description":"A black-and-white animated line traces a double pendulum motion, with two connected arms sweeping from a fixed center point and a small circle riding at the tip. The circle alternates between white and black fills while a larger shadow circle follows underneath. The animation updates every 50 milliseconds using JavaScript’s `setInterval`, and d3 v6 selection methods like `selectAll`, `data`, and `join` bind new positions to SVG `<line>` and `<circle>` elements.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3f2c9da9c71340239c91e711ab97560f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
