{"version":"1.0","type":"rich","title":"Fork of MuscleCars tree","description":"This fork displays a hierarchical tree of muscle cars organized by manufacturer, using D3 v3’s `d3.layout.tree` with SVG rendering and animated node transitions. The visualization reads hierarchical JSON data and encodes each node’s type with a distinct fill color (grey, blue, red, orange). Interactive zooming and dragging are enabled via `d3.behavior.zoom`, and node clicks collapse or expand subtrees. The code also defines custom link paths with arrow markers and tooltips, while collision detection and breadth-first traversal position nodes without overlap.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/bf91169cd01042b099c12dfff442f55b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
