{"version":"1.0","type":"rich","title":"Fork of World Countries Hierarchy","description":"A hierarchical tree visualization displays the world’s countries, organized by continent and then by subregion (e.g., Southern Asia, Western Asia). Node labels use the `Playfair Display` serif font, with font size decreasing by tree depth. The chart is rendered as an SVG using `d3.tree`, `d3.hierarchy`, `d3.linkHorizontal`, and `d3.zoom`. It loads `data.json` and uses `root.descendants()` to place text labels and generate paths for the links between nodes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5ed40ac1f10b4798ae27565a310a05b6?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
