{"version":"1.0","type":"rich","title":"Fork of World Countries Tree","description":"This D3.js v5 visualization presents a hierarchical tree of world countries, organized by continent and subregion, using a horizontal icicle layout. The chart shows the geographic grouping of nations from a JSON data source, with each node labeled by country name and positioned by depth. The code leverages D3's `tree`, `hierarchy`, and `linkHorizontal` functions to compute the layout and draw connecting paths. Interactive pan and zoom are enabled through D3's `zoom` event, while text styling uses the Playfair Display font.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7a341c3b031a4cf7aa93a55917984464?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
