{"version":"1.0","type":"rich","title":"Fork of Double Harmonic","description":"This example shows a double pendulum animation, drawing a small ball as the endpoint of two connected, rotating line segments. The code uses d3.js v6 with a time-driven `setInterval` loop to update the pendulum's position based on a constant time step and a phase-shift ratio (`psi`). It renders the scene as SVG, creating the arm lines, a moving ball, and a large hollow circle marker at the endpoint. The visualization demonstrates the harmonic motion of the two-segment system.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/629434db3f884fd480d27ac13e3ed88b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
