{"version":"1.0","type":"rich","title":"World Countries Tree","description":"This visualization shows a hierarchical tree of world countries, organized by continent and subregion. It maps the geographic hierarchy of nations into a horizontal icicle-style layout. The D3.js v5 code uses the `tree` layout, `hierarchy`, and `linkHorizontal` functions to position nodes and draw connecting paths. Text labels are rendered with variable font sizes based on depth, and the SVG supports pan and zoom through a `zoom` event. The data is loaded from a local JSON file containing the full country and regional structure.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f38ad8b77a4841c0a1f092a8cbd06711?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
