{"version":"1.0","type":"rich","title":"World Countries Tree","description":"This visualization presents the World Countries Tree, a hierarchical layout of global geography organized from continents down to individual nations. Built with D3 v5, it employs the `tree()` layout and `linkHorizontal()` path generator to create an interactive, zoomable SVG diagram. The hierarchical data structure, loaded from a JSON file, defines parent-child relationships between regions. Users can pan and zoom using D3’s `zoom()` behavior, while text labels scale in size based on depth, emphasizing the tree’s branching structure.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2ce34fcb3dff4ccdb623a885935ae65f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
