{"version":"1.0","type":"rich","title":"Fork of World Countries Tree","description":"The visualization displays a hierarchical tree of world countries, organized by continent and region. It reads a JSON file containing the country hierarchy and renders it as an indented tree layout. The code uses d3's `hierarchy`, `tree`, and `linkHorizontal` functions to compute the layout and draw connection paths. Text labels show country names, with a zoom feature enabled via the `zoom` event, allowing interactive navigation of the tree structure.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e9cacb192abd472fb6f52072e45f09db?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
