{"version":"1.0","type":"rich","title":"World Countries Tree","description":"This visualization presents the hierarchical structure of world countries, organized by continent and subregion. The tree layout renders the data as a branching diagram, with each node labeled by its geographic name. The visualization uses D3 v5's `tree` and `hierarchy` functions to compute the layout, and `linkHorizontal` to draw the connecting paths. Users can pan and zoom the SVG canvas using D3's `zoom` behavior. The data describes countries grouped under regions like Asia, which is further divided into subregions such as Southern and Western Asia.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9116233711c3459d93e5654df315a244?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
