{"version":"1.0","type":"rich","title":"World Contries Tree","description":"This example visualizes the hierarchical structure of countries grouped by continent and subregion, using a horizontal tree layout from a JSON dataset. Parent nodes are labeled with larger text, and each leaf represents a country. The visualization is built with D3.js v5, using `d3.tree`, `d3.hierarchy`, and `d3.linkHorizontal` for rendering SVG paths and text. Pan and zoom interactions are enabled via `d3.zoom`, with the tree rendered in an SVG container.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/839334b8fb0647b49ce8ad3cc2dee2c5?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
