The root node (World) is blue, continents are purple, and country leaf nodes are green, with a color-coded legend on the right. The visualization uses the D3.js v7 `d3.tree()` layout, `d3.hierarchy()`, and `d3.linkVertical()` to compute and draw the SVG paths and circles. The data is a hardcoded JavaScript object representing the geographic parent-child relationships.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ec1402e01b3a46f4b508ea7eb4008796?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
