{"version":"1.0","type":"rich","title":"World Countries Tree with D3.js!","description":"This example visualizes the hierarchical relationships among world countries and regions as a collapsible-style tree. It displays continents branching into subregions and individual countries, using a horizontal layout with adjustable text size based on depth. The visualization implements pan and zoom functionality through D3’s `zoom` behavior, applying the transform to an SVG group. The tree structure is generated with `d3.hierarchy` and `d3.tree`, while curved links are drawn using `d3.linkHorizontal` from a local `data.json` file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6582628533ee4539b59b3b8e4e3b16e7?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
