{"version":"1.0","type":"rich","title":"Activity8_task6_MuscleCars tree","description":"This example shows an animated, interactive tree diagram of muscle car models, branching from a root node through Ford and Dodge to specific vehicles and their trims. Built with D3 v3, it renders the hierarchy as an SVG using a collapsible tree layout (`d3.layout.tree`), with colored rectangles for nodes, links, and arrow markers defined in a `defs` section. The code supports zoom and drag via `d3.behavior.zoom`, and includes tooltips and collision detection between nodes. Data comes from a local `Tree.json` file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2123cc6cf3234d9a8142fb0173fe6a74?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
