{"version":"1.0","type":"rich","title":"Tree 7","description":"This example shows an interactive tree diagram of hospital departments, with nodes labeled by location or clinic name (e.g., KFSH, Riyad, Dental). Clicking a node collapses or expands its children with a smooth animated transition. The visualization uses D3 v3’s `d3.layout.tree` to compute node positions and `d3.svg.diagonal` for curved link paths. Data is loaded from an external JSON file, and SVG elements are updated via D3’s enter/update/exit pattern with a 1100-millisecond duration.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/956de08c4b4841cda37b083c31e6c1ed?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
