{"version":"1.0","type":"rich","title":"Fork of World Countries Tree","description":"This fork of the World Countries Tree visualizes the hierarchical structure of countries by continent and subregion, using an indented tree layout. The code leverages d3.js v5 APIs, including `d3.select`, `d3.json`, `d3.tree`, and `d3.hierachy`, to load a nested `data.json` file and render the structure as an SVG. Nodes are connected by teal paths, with country names displayed in a serif font, while the layout dynamically fills the browser viewport.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2d1297c5c168408cae3b569e9bea57b0?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
