{"version":"1.0","type":"rich","title":"Fork of Fork of Radial Tree of Countries Hierarchy","description":"A radial tree diagram displays a hierarchical classification of countries by world region and subregion, sourced from a JSON file named `countryHierarchy.json`. The visualization shows the World as the root, branching into continents like Asia, then subregions such as Southern Asia, and finally individual countries. Built with D3.js v4, the code uses `d3.cluster` to compute the tree layout and `d3.hierarchy` to process the data. Nodes and connecting links are rendered as SVG elements, while `d3.zoom` enables panning and scaling. Text labels are positioned radially, with rotation adjusted based on each node's angle.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/bde9a617b3a640939b9fcee047f2cacd?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
