{"version":"1.0","type":"rich","title":"Double Harmonic","description":"Two concentric pendulum arms trace a slowly evolving path. A large circle rotates around the center, and a smaller circle rotates around it, creating a complex harmonic motion. The visualization uses SVG elements, including circles and lines, and is updated at a fixed interval. The code employs D3’s `select`, `range`, and data join methods to render the animation, based on the `d3` library version 6.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/003accf7d862422b83634396dc1196de?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
