{"version":"1.0","type":"rich","title":"Fork of Fork of World Countries Tree","description":"This example shows a hierarchical tree of world countries arranged by continent and subregion, with each country name displayed in increasingly smaller text as the depth increases. The visualization uses D3 v5’s `tree` layout and `hierarchy` to structure the data, with `linkHorizontal` generating curved path links between nodes. Pan and zoom interactions are enabled via `d3.zoom`, and the SVG rendering applies a fixed stroke color for paths and a serif font with a text shadow for labels. The data comes from a nested JSON file containing geographic groupings.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/40287959c729465d8de53a083c937ded?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
