{"version":"1.0","type":"rich","title":"Fork of World Countries Tree","description":"This visualization presents a hierarchical tree of world countries, organized by continent and subregion, with each country labeled as a leaf node. The tree layout positions nodes horizontally, with links drawn as curved paths and text labels scaled by depth. Built with D3 v5, it uses `d3.tree`, `d3.hierarchy`, and `d3.linkHorizontal` to compute and render the layout, while a zoom behavior enables panning and scaling of the SVG canvas. The data is loaded from a JSON file, and the styling uses a serif font with orange link strokes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5395675f1c50481cae7c4f6be75b4304?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
