{"version":"1.0","type":"rich","title":"Fork of Double Harmonic","description":"A two-link pendulum traces a spherical path as two connected circles rotate around a fixed center point. The animation uses `setInterval` to update the positions every 50 milliseconds, with the second circle’s motion offset by a constant psi value that creates the harmonic fork effect. The SVG rendering uses `selectAll` and `join` to update circle and line elements, applying black strokes for the pendulum arms and a white circle with a black border for the joint. The visualization responds to browser window dimensions, setting its size based on `window.innerWidth` and `window.innerHeight`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/93e67b3978e542128589c65dc3ad860b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
