{"version":"1.0","type":"rich","title":"Radial Tree of Countries Hierarchy","description":"This radial tree visualization displays the hierarchical structure of world countries, organized by continent and subregion. Built with d3.v4, it uses the d3.cluster layout to position nodes in a circular arrangement, with SVG paths connecting parent and child nodes. The visualization supports panning and zooming interactions through d3.zoom, and text labels are rotated and sized based on their depth within the hierarchy, with the data sourced from a nested JSON file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6771ba38b39542a1a8f51662cd41c41f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
