{"version":"1.0","type":"rich","title":"Tree Graph ICE 8","description":"A tree diagram shows the hierarchical structure of global health data, with countries (Brazil, India, Australia, Nigeria) branching into disease categories and specific diseases. The visualization uses a horizontal tree layout with colored nodes—orange for countries, light blue for disease categories, and green for diseases—to distinguish hierarchy levels. The code employs D3 v7's `d3.hierarchy` and `d3.tree` APIs to compute layout positions, and renders the SVG with `linkHorizontal` paths and circles via a `.join()` operation. A legend above the chart explains the color coding.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8aa47c578aed465ebc810d89afb4ed6b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
