{"version":"1.0","type":"rich","title":"Fork of World Countries Tree","description":"This visualization displays a hierarchical tree of world countries, organized by region, extending from a root node labeled with a personal name. It uses the D3.js v5 library, specifically `d3.tree` for layout and `d3.linkHorizontal` for edge paths, to render an SVG graphic. The data loads from a JSON file and supports panning and zooming via the `d3.zoom` API. Node labels vary in font size based on their depth in the hierarchy, making the structure readable while emphasizing the broader regional groupings and individual countries.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7f2fa5fa135c4ed496392f39096f3251?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
