{"version":"1.0","type":"rich","title":"Data Tree","description":"This visualization shows a hierarchical tree of world regions and countries, with countries nested under their respective continents and subregions. The tree is rendered with SVG paths connecting parent and child nodes, using a horizontal layout where text labels display country names at sizes that decrease with depth. The code uses D3 v5’s `tree`, `hierarchy`, and `linkHorizontal` APIs to compute the layout, and includes zoom functionality via `d3.zoom`. Data comes from a static JSON file containing the geographic hierarchy.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/331af1ecfd61409c9e2d2e6aaf5573e1?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
