{"version":"1.0","type":"rich","title":"world countries tree","description":"This visualization displays a hierarchical tree of world countries, organized by continent and subregion. The data branches from the root node \"World\" down to individual nations, with each level representing a geographic grouping. The code uses D3 v5’s `tree` layout and `hierarchy` function to compute node positions, while `linkHorizontal` generates the curved connector paths. Country and region names are rendered as SVG text elements, with the tree laid out horizontally across the full viewport. The styling applies a cyan stroke to the links and a white text shadow for readability.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c7b4970fb4294d8c84243cde11491fb7?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
