{"version":"1.0","type":"rich","title":"World Countries Tree-labels","description":"This example shows a hierarchical tree layout of world countries, organized by continent and subregion, with each country name displayed as a text label. The visualization uses D3 v6’s `tree` layout and `linkHorizontal` path generator to draw curved links between parent and child nodes. Labels are rendered as SVG `<text>` elements with font sizes decreasing by depth, and a D3 `zoom` behavior enables panning and scaling. The data is loaded from a local JSON file, and white text shadows improve readability over the drawn paths.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9136f7ee74ea4fe19cefc7690d2cd71e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
