{"version":"1.0","type":"rich","title":"Fork of World Countries Tree","description":"The World Countries Tree visualizes a hierarchical dataset of countries organized by continent and subregion as a labeled, zoomable tree diagram. It uses D3's `tree` layout and `linkHorizontal` path generator to draw curved links between nodes, rendering text labels whose font size decreases with depth. Implemented with D3 v5, the chart supports interactive pan and zoom through `d3.zoom`, with an SVG container and data loaded from a static JSON file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/248b75b965874439b8a73b3ca9da0da9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
