{"version":"1.0","type":"rich","title":"World Countries Tree","description":"This example shows a hierarchical tree of world countries organized by continent and region, with nodes connected by curved links. The visualization uses D3 v5’s `tree` layout and `linkHorizontal` path generator to position and draw the hierarchy, rendering the structure as SVG paths. Data comes from a JSON file with nested `children` arrays, and the view supports interactive zooming through D3’s `zoom` behavior. The styling applies a custom Playfair Display font and a teal stroke color to the links.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c90998e8a7954abb8515c2a277e9b514?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
