{"version":"1.0","type":"rich","title":"world countries tree","description":"This is an interactive, hierarchical tree visualization that displays a global breakdown of countries, organized by continent and region, with the root node labeled \"World\". The data is rendered as a horizontal tree layout, with labeled text nodes and connecting lines. The implementation uses D3.js to build the tree structure, with `d3.hierarchy` and `d3.tree` computing the layout, and `d3.linkHorizontal` generating the connecting paths. The visualization supports zooming and panning via the `d3.zoom` module, and text styling uses the Raleway font.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b0188fa763634b1a8dedf59cbaa929a8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
