{"version":"1.0","type":"rich","title":"RADIAL TREE","description":"This radial tree visualization displays a hierarchical dataset of world countries, organized by continent and subregion. Built with D3 v4, it uses the `d3.cluster` layout to position leaf nodes around a circular arc, with curved `path` links connecting parent and child nodes. The SVG rendering includes size-scaled text based on node depth and supports panning and zooming via `d3.zoom`. Node labels are rotated adaptively for readability, and a glow effect is applied to non-leaf labels via CSS `text-shadow`. The data is loaded from a JSON file using `d3.json`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/fafc8dbb401b4b5cb9b21ae032547592?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
