{"version":"1.0","type":"rich","title":"MuscleCars tree","description":"This example shows a hierarchical tree of muscle cars organized by manufacturer, with Ford and Dodge as the top-level brands and individual models like Mustang, Torino, Charger, and Challenger as leaf nodes. The tree uses a D3 v3 layout with color-coded rectangular nodes (grey for the root, blue for manufacturers, red for models, orange for sub-models) and animated SVG rendering. The visualization supports zooming and panning through d3.behavior.zoom, and each node has a dropdown shadow and arrow markers. The data is loaded asynchronously from a JSON file that defines the tree structure.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/09e78c05c36144e298512fd2a2c705f4?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
