{"version":"1.0","type":"rich","title":"Fork of D3 Selection Exploration","description":"Two clusters of thin vertical rectangles orbit and pulse around a central point, alternating between red and pink fills as they shift position every frame. The animation runs on a 60fps interval, regenerating a 30-point dataset from sine and cosine functions to update each rectangle's x, y, and fill properties. The example uses D3 v6 selections with `.data()` and `.join(\"rect\")` to bind the dynamic data to SVG elements, while the commented-out circle code and `vizData` module suggest alternative rendering approaches.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
