{"version":"1.0","type":"rich","title":"Let's make a map with D3.js!","description":"This example renders a hierarchical tree visualization of world regions and countries using D3.js v5. The data is loaded from a JSON file that organizes countries under continents and subregions, which is then processed with the `d3.hierarchy` and `d3.tree` layouts. SVG paths are generated for the links using `d3.linkVertical`, with the tree layout’s size set to the full browser window dimensions. The map-like structure is drawn solely as a node-link diagram, not a geographic projection.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ece24227cb3146e284b5371ed00d86fd?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
