{"version":"1.0","type":"rich","title":"RADIAL TREE","description":"This visualization shows the hierarchical structure of world countries organized by continent and subregion, displayed in a radial tree layout. The data comes from a JSON file containing country names grouped into regional categories. Built with D3 v4, the code uses `d3.cluster` and `d3.hierarchy` to compute the radial positions, while `d3.zoom` enables panning and zooming. Labels are rotated and positioned based on depth, with larger fonts for higher-level nodes, and rendered as SVG text with a glow effect.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f3cb96fee0244bf4b0b4ed733dfb6ac4?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
