{"version":"1.0","type":"rich","title":"World Countries Tree","description":"This interactive visualization presents a hierarchical tree of world countries, rendered as a horizontal network of nodes and links in an SVG. The data, loaded from a JSON file, is arranged using the D3.js tree layout, with link paths generated by `linkHorizontal` and node labels positioned by depth. Users can pan and zoom the entire diagram via the D3 zoom behavior, which applies transforms to a group element. The styling uses a serif font and teal strokes, with font size scaling inversely to node depth to emphasize the root hierarchy.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/00ecd2f6e5fd4a219095048b57029106?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
