{"version":"1.0","type":"rich","title":"wejdan map","description":"This interactive visualization displays a hierarchical tree of world regions and countries, branching from continents down to individual nations. The tree layout positions parent nodes with centered labels while child countries extend outward with left-aligned text, using font size to indicate depth. Built with D3.js v5, the code employs `d3.tree`, `d3.hierarchy`, and `d3.linkHorizontal` to generate the SVG paths and text elements from a nested JSON dataset. Users can pan and zoom the map via `d3.zoom`, with a teal stroke connecting the hierarchical structure.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3b420da6dc6f4093bffe6c987460fae1?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
