{"version":"1.0","type":"rich","title":"World Countries Tree","description":"This example visualizes a hierarchical network of virtual components, from a root \"Virtual Network\" down through subnets, network security groups, and virtual machines to network interfaces and IP addresses. Using D3 v5, it renders a vertical tree layout with `d3.tree()` and `d3.hierarchy()`, drawing nodes as pink rectangles and light blue circles on an SVG canvas. The code employs `d3.linkVertical()` for edge paths and `d3.zoom()` for pan and zoom interactions. Data comes from a local `data.json` file, loaded asynchronously via `d3.json()`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/62853c1c2a3344ad985c15a0742205c5?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
