{"version":"1.0","type":"rich","title":"Tree Chart","description":"An animated hierarchical tree chart displays a dataset of continents, countries, cities, and local landmarks, with nodes color-coded by level: black for roots, blue for countries, red for cities, and green for landmarks. The visualization uses D3.js version 3 layout and diagonal SVG paths, with an in-memory JSON array as the data source. Transitions animate the tree’s expansion, while styling from CSS handles node circles and text.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
