{"version":"1.0","type":"rich","title":"Reverse Collatz","description":"This visualization animates the reverse Collatz conjecture, building a radial tree that shows which numbers lead to a given value through the inverse of the rule (odd numbers become 3n+1, evens are halved). Starting from 1, each level adds the possible predecessors, revealing the branching structure of the conjecture. The code uses `d3.layout` from D3 v5 to compute the hierarchical layout, with SVG circles and text labels rendered in a radial arrangement. An interactive slider and play button control the depth of the tree, with smooth transitions via D3's `transition()` API as new levels unfold.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/f1751a2f34ad4d3da2b2f86657e0fca5?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
