{"version":"1.0","type":"rich","title":"Untitled","description":"Twenty colored rectangles of random sizes bounce off one another and the edges of an SVG canvas, continuously accelerated by a custom force simulation built with `d3.forceSimulation`. Each particle moves at a constant velocity, with a custom `rectCollide` force handling pairwise collisions via a quadtree, and a `boundedBox` force keeping them inside the frame. Rectangles are draggable with `d3.drag`, which temporarily alters their velocity. The visualization uses D3 v4 with ordinal color scaling and direct SVG manipulation.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6a4d63974cb64e6e8cf07d963c516fd9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
