{"version":"1.0","type":"rich","title":"Fork of World Countries Tree","description":"This visualization displays the hierarchical structure of world countries, organized by continent and subregion, as a horizontal tree diagram. The data is loaded from a local JSON file and rendered as SVG using D3 v5. It uses `d3.tree` and `d3.hierarchy` to compute the layout, `d3.linkHorizontal` for the connecting paths, and a zoom behavior for panning and scaling. Node labels are positioned dynamically, with font size decreasing by depth, and text shadows improve readability.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/146dcfbdcd644f20bba273ac015a674f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
