{"version":"1.0","type":"rich","title":"World Countries Tree","description":"This example displays a hierarchical tree of software components and projects, using a dataset of Ericsson product areas with nested submodules. The code loads `data.json`, applies the `d3.tree` layout, and renders the structure with SVG `path` elements and `text` labels. It uses `d3.hierarchy`, `linkHorizontal` for curved links, and `d3.zoom` for pan-and-zoom interaction. Font sizing decreases with node depth, and the styling relies on the Playfair Display typeface with a custom color for the links.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/61bf4b46755d4b839c367b283347539d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
