{"version":"1.0","type":"rich","title":"tree visualization of countries","description":"This tree visualization displays the hierarchical structure of countries organized by continent and subregion, using data from a JSON file. The visualization employs a D3 tree layout with hierarchical links rendered as horizontal paths. SVG text labels show country names with font sizes that decrease with depth. The chart supports zooming and panning through D3’s zoom behavior, while the styling uses CSS with subtle text shadows and a serif font for readability.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a5155a70d079483bb3fbd454b01cc9a5?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
