{"version":"1.0","type":"rich","title":"Tree Visualization of World Countries","description":"This visualization displays the hierarchical relationship between world countries, continents, and subregions as a horizontal tree diagram. The code uses D3 v5’s `tree` and `hierarchy` layouts to compute node positions, with `linkHorizontal` generating curved connecting paths. Text labels show country names at varying font sizes based on tree depth. The SVG rendering supports zooming and panning through D3’s `zoom` behavior, and the data comes from a nested JSON file. The styling uses the IM Fell English SC font.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a1236ffa6b9647a2af783a0cea5bd244?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
