{"version":"1.0","type":"rich","title":"Radial Tree","description":"A radial tree displays a hierarchical dataset of world countries, branching outward from a central root with nodes arranged by depth. The visualization supports panning and zooming to explore the structure. Built with D3 v4, it uses `d3.stratify` to parse the data, `d3.tree()` with a radial layout, and `d3.linkRadial` for curved links. Node labels rotate based on depth and angle, with font sizes decreasing for deeper levels. The scene is rendered as SVG within a fixed-size viewport.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/56e1ee2994fe4b0cb59562d41249bff7?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
