{"version":"1.0","type":"rich","title":"World Countries Tree","description":"This interactive world map displays the hierarchical structure of countries, organized by continent and subregion, as a horizontal tree diagram. The visualization uses `d3.hierarchy` to process the nested JSON structure and `d3.tree` to compute the layout based on the data's size and dimensions. A `d3.zoom` interaction is applied to the SVG container, allowing users to pan and scale the entire tree. The edges are rendered using the `d3.linkHorizontal` generator, while each node's label is positioned with a font size that inversely corresponds to its depth in the hierarchy, with the text styling set via CSS.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5201fcc334d145b0a1b65d40cc76b26b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
