{"version":"1.0","type":"rich","title":"World countries tree","description":"This example visualizes hierarchical survey data as a radial tree, with each leaf node represented by a colored horizontal bar showing a percentage value and its associated words array listed underneath. Built with D3 v5 and SVG, the code uses `d3.hierarchy`, `d3.cluster`, and `d3.scaleLinear` to compute the layout and encode numeric values as bar heights. Labels and bars are positioned along the circular hierarchy, and the visualization loads data from a JSON file containing nested topic clusters with word lists, as well as support for panning and zooming via `d3.zoom`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5dc04ec3ee6b4a3187a3fae69aa79710?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
