{"version":"1.0","type":"rich","title":"Fork of tree visualization of countries","description":"This example displays a hierarchical tree visualization of countries organized by continent and subregion, with the root node labeled “World” and leaves representing individual nations. The data is loaded from a JSON file and rendered as an SVG using D3 v7’s `tree` layout, `hierarchy`, and `linkHorizontal` generators. Nodes are labeled with text whose font size decreases with depth, while curved links are styled with a teal stroke. Pan and zoom interactions are enabled via `d3.zoom`, and the layout adapts to the browser window dimensions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3c05f443b6af4fad8350ce35b12d4dca?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
