{"version":"1.0","type":"rich","title":"Fork of Radial Tree of Countries Hierarchy","description":"This radial tree diagram visualizes the hierarchical structure of migrant worker demographics, displaying categories such as background, distribution, industry type, and basic characteristics. The visualization uses D3 v4’s `d3.cluster()` layout to position nodes radially around a central root, with `d3.zoom()` enabling pan and zoom interactions. The SVG rendering applies curved link paths between parent and child nodes, while font size scales with node depth via `d3.scaleSqrt()`. Text labels rotate based on angular position, with leaf nodes aligned outward for improved readability.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/227af9f29ae54afd9c14218bf4c6a4ff?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
