{"version":"1.0","type":"rich","title":"D3TreeTest","description":"This example shows a hierarchical tree visualization of world countries, organized by continent and region, with a zoomable SVG canvas. The code uses D3 v5’s `tree()` layout, `hierarchy()`, and `linkHorizontal()` to position nodes and draw curved links between parent and child elements. It loads the hierarchical structure from `data.json` via `json()`, and renders country names as text with font sizes scaled by node depth. The zoom behavior is enabled through `d3.zoom()`, allowing users to pan and scale the tree.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c6266c63f94842f8a8220afdb061db73?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
