{"version":"1.0","type":"rich","title":"World Countries Tree!","description":"This example displays a hierarchical tree of world countries, organized by continent and subregion, with the data read from a local JSON file. The visualization uses D3.js to build the tree with a horizontal link layout, rendering nodes as text labels of varying font sizes based on their depth in the hierarchy. The SVG canvas supports zooming and panning through a custom zoom function, and the code employs D3's hierarchy, tree, and linkHorizontal APIs to position elements.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b8ec0eb7724a4024abc50c3f2bb4a09a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
