{"version":"1.0","type":"rich","title":"World Countries Tree","description":"This visualization displays a hierarchical tree of world countries organized by continent and subregion, using a left-to-right layout with curved links and text labels sized by depth. The data is loaded from a JSON file and processed with `d3.hierarchy` and `d3.tree`, while `d3.linkHorizontal` generates the paths and `d3.zoom` enables panning and zooming on the SVG. Text styling relies on CSS `text-shadow` for readability, and the layout adapts to the full browser viewport.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/17e879e790aa4c3198bbdebb4ce676c0?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
