{"version":"1.0","type":"rich","title":"World Countries Tree","description":"The World Countries Tree visualizes the hierarchical structure of global geography, from continents through subregions down to individual countries, using a horizontal tree layout rendered as SVG. It employs D3 v5’s `tree` and `hierarchy` functions to compute the layout, `linkHorizontal` for curved connector paths, and a zoom behavior for interactive panning and scaling. Font sizes decrease with tree depth, and the dataset is loaded from a local `data.json` file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/599e687878654e578a12c351fb98187b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
