{"version":"1.0","type":"rich","title":"Fork of World Countries Tree","description":"This visualization shows the hierarchical structure of world countries, organized from continents to subregions to individual nations, displayed as a horizontal tree diagram. The data comes from a JSON file containing geographic groupings. Built with D3 v5, it uses `d3.hierarchy`, `d3.tree`, and `d3.linkHorizontal` to generate the SVG layout, while `d3.zoom` enables pan and zoom interaction. Node labels are rendered as text with decreasing font sizes based on tree depth.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/bbd8eda0b1144f9f89a4c53ac5e695c7?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
