{"version":"1.0","type":"rich","title":"Fork of World Countries Tree","description":"This fork of the World Countries Tree visualization displays a hierarchical dataset from data.json, where a root node labeled “Father” branches into seventy identical children named “Joe.” The D3.js v7 code uses `tree()` layout and `linkVertical()` to draw connecting paths, with text labels rotated for leaf nodes. SVG rendering supports interactive zooming via `zoom()`, while font sizes scale dynamically based on sibling count using the imported `scale` API.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1ab46394dfe64b819a15bcdb8cacb270?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
