{"version":"1.0","type":"rich","title":"ICE 8 tree","description":"This compact world tree uses a hierarchical layout to visualize a small dataset of continents and countries. The root node represents the World, with continents as blue circles and countries as green ellipses. Implemented with D3.js v7, it uses `d3.hierarchy` and `d3.tree` to compute node positions, with `d3.linkVertical` drawing the connecting links. The SVG is styled via CSS variables, and node shapes vary by type, while labels are added as text elements.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/35e672ebf6594b63a50a8c61df6f2bba?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
