{"version":"1.0","type":"rich","title":"World Countries Tree","description":"This visualization displays the hierarchical structure of world countries, organized by continent and subregion, as a horizontal tree diagram rendered in SVG. Using D3 v5's `tree()`, `hierarchy()`, and `linkHorizontal()` APIs, the code reads a JSON data file and positions nodes and connecting paths based on the computed layout. Country names are rendered as text labels with white text shadows, while the paths use a teal stroke. The visualization fills the entire browser viewport, with the page set to fixed positioning and overflow hidden.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ec9b2e499b904c1fa8722f224f78adb3?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
