{"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. The root node represents the data source, with branches expanding outward to reveal geographic groupings and individual countries. The code uses D3.js v5, implementing a tree layout with `d3.tree()` and `d3.hierarchy()` to process hierarchical JSON data. Nodes are rendered as SVG text elements connected by horizontal links generated with `d3.linkHorizontal()`, and the entire visualization supports pan and zoom through D3’s zoom behavior.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a198f6cc73b84cde9c9097c790766178?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
