{"version":"1.0","type":"rich","title":"World Countries Tree","description":"This visualization shows a hierarchical tree of world countries, organized by continent and subregion, with the country names displayed as text labels. The tree layout uses `d3.tree` and `d3.hierarchy` to position nodes, while `d3.linkHorizontal` generates curved paths for the connections. The SVG rendering includes zoom functionality via `d3.zoom`, allowing interactive pan and scale. Data is loaded from a JSON file containing geographical groupings, and text styling uses the Playfair Display font with font sizes that decrease with node depth.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2b66d616597742248aa3cc64a6a0dc78?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
