{"version":"1.0","type":"rich","title":"Activity 8 Q6A","description":"This example presents an interactive hierarchical tree visualization of muscle car models, using D3.js v3 to render SVG elements with click-to-expand/collapse functionality. The tree layout arranges nodes by type, with color-coded rectangles representing different model categories (Grey, Blue, Red, Orange) and arrowed links indicating parent-child relationships. The visualization includes zoom and drag behavior via `d3.behavior.zoom`, plus tooltips and drop-shadow filters defined in SVG defs. Data is loaded asynchronously from a JSON file and rendered within a 350-pixel-wide container with animated transitions between states.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/29adfde6ec3f4aedaea64273cd3d1260?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
