{"version":"1.0","type":"rich","title":"world countries tree","description":"This example shows a hierarchical tree of world countries, organized by continent and subregion, with each country name displayed as a text label. The visualization renders an SVG using D3.js v5, leveraging the `tree` and `hierarchy` layouts to compute node positions and `linkHorizontal` to draw curved paths between parent and child nodes. Data is loaded from a local JSON file, and text labels are offset with a dy attribute for readability.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/064be259e3c441a98bf4729373484e25?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
