{"version":"1.0","type":"rich","title":"World Countries Tree","description":"This visualization shows the hierarchical organization of world countries, grouped by continent and subregion, as a horizontal tree layout. It uses D3 v5’s `tree` layout and `hierarchy` to compute node positions, with `linkHorizontal` drawing curved edges between levels. Country and region names are rendered as SVG text, with font size decreasing by depth. The view supports pan and zoom via D3’s `zoom` behavior, and data is loaded from a local `data.json` file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7c7de0515ec9499dae6a935348bdbba6?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
