{"version":"1.0","type":"rich","title":"Fork of World Countries Tree","description":"This tree visualization displays the hierarchical structure of world countries, with nodes labeled by country identifiers and connected by curved paths. The layout uses `d3.tree` and `d3.hierarchy` to compute positions, while `d3.linkHorizontal` generates the links. The SVG renders with a green stroke for paths and serif text, with font size decreasing by node depth. The visualization supports pan and zoom through `d3.zoom`, applied to a background rectangle. Data is loaded from a local `data.json` file, and the code uses D3 v5 via ES modules.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/aa70e87dfaba4b87ac2cc163ea1b8351?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
