{"version":"1.0","type":"rich","title":"MuscleCars tree","description":"This interactive tree diagram visualizes the hierarchy of muscle car manufacturers, showing Ford and Dodge as top-level brands that branch into specific models like the Mustang, Torino, Charger, Challenger, and their performance variants such as Hellcat and SRT. The visualization uses D3.js v3 with an SVG-based layout to render nodes and links, with each node color-coded by type level and featuring expandable/collapsible interactions, zooming, drag functionality, and tooltips. The implementation relies on `d3.layout.tree` for structure, `d3.behavior.zoom` for navigation, and custom CSS for styling, with data loaded from a JSON file defining the tree hierarchy.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6b68b4f6ad5c4192b5c5eff4950e7079?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
