{"version":"1.0","type":"rich","title":"Fork of World Countries Tree","description":"A collapsible tree charts the hierarchical relationship of world continents, regions, and countries, parsed from a JSON dataset. The visualization uses D3 v5’s `tree` layout and `hierarchy` to structure the data, then renders nodes as text labels and links as horizontal paths via `linkHorizontal`. A zoom behavior enables panning and scaling of the SVG canvas. Labels adjust font size based on depth, with intermediate nodes centered and leaf countries left-aligned, styled with a serif font and white text shadow.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/347798e2c04342bc821c0db7d07695ae?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
