{"version":"1.0","type":"rich","title":"World Countries Tree","description":"This visualization shows the hierarchical structure of world countries, organized by continent and subregion, as a horizontal tree diagram. It uses D3 v5’s `tree()` layout and `hierarchy()` to compute node positions, with `linkHorizontal()` drawing curved paths between parent and child nodes. Each country name is rendered as SVG text, with font size decreasing by depth. The view supports zooming and panning via D3’s `zoom()` behavior, applied to a containing `<g>` element. Data is loaded from a local `data.json` file, and styling uses the Playfair Display font.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ecd2b18dcbbb46dd87ef6bd108763ebf?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
