{"version":"1.0","type":"rich","title":"Fork of World Countries Tree","description":"This visualization displays a hierarchical tree of world countries organized by continent and subregion, with each leaf node representing a country rendered as text. Using the D3 v5 tree layout, the code converts nested JSON data into a horizontal dendrogram, connecting parent-child relationships with curved paths generated by `linkHorizontal`. Text nodes are positioned via `d3.hierarchy` and styled with font sizes decreasing by depth. The SVG output supports pan and zoom through D3’s `zoom` behavior, while labels include white text-shadows for readability against the teal link strokes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c5fc116c4b654fbbb42e57b02d68834a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
