{"version":"1.0","type":"rich","title":"Tree Example","description":"This interactive tree diagram displays the hierarchical structure of a dataset, with nodes and links rendered using SVG and animated transitions. The visualization uses D3.js version 3, with the `d3.layout.tree` for layout and `d3.svg.diagonal` for curved links. Clicking nodes expands or collapses their children, with smooth transitions achieved through `transition.attr`. The static data is embedded in the code, and the example also includes a separate CSV file for population data, though it is not referenced in the visualization.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/83d584439baf4645842a4e63e43c343c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
