{"version":"1.0","type":"rich","title":"World Countries Tree","description":"This example visualizes the hierarchy of world countries using a tree diagram. The root node represents the World, branching into continents, subregions, and finally individual countries based on the data.json structure. The tree is rendered with D3.js v5, using the `d3.tree` layout, `d3.hierarchy`, and `d3.linkHorizontal` for the edges. The SVG is drawn with text labels and styled paths, and a `d3.zoom` component enables interactive pan and zoom.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/25eeebec4d414fe7911ad07d37aaf29f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
