{"version":"1.0","type":"rich","title":"World Countries Tree with D3.js!","description":"This visualization presents a hierarchical tree of world countries, organized by continent and sub-region based on a nested JSON data structure. The tree renders as an indented horizontal layout using SVG paths and text elements, with the D3.js library managing the layout calculations. The code leverages D3's `tree`, `hierarchy`, and `linkHorizontal` APIs to position nodes and draw connecting lines, while a zoom interaction via `d3.zoom` allows panning and scaling. The styling uses a custom serif font and white text shadows for readability.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/dab5b8ca11cf4490bfce67a8d3625d7d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
