{"version":"1.0","type":"rich","title":"Fork of Double Harmonic","description":"A double pendulum animation built with D3.js v6 renders a black tracing line and white ball in SVG. The code uses `select`, `range`, and `setInterval` to update circle and line positions at each tick, computing the pendulum’s path from cosine and sine functions with a fixed psi ratio. The full-screen SVG shows two connected rods and the swinging tip, with ball radius and arm lengths as constants.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5befbad368a44423b4aea3d5412b1611?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
