{"version":"1.0","type":"rich","title":"Art Tree","description":"This hierarchical tree chart displays a global geographic classification, starting with \"World\" and branching through continents and subregions down to individual countries. The visualization uses a horizontal link-and-node layout, with the root node on the left and child nodes extending rightward. Built with D3 v5, the implementation calls `d3.tree` and `d3.hierarchy` to structure the data, then uses `d3.linkHorizontal` to generate the curved SVG paths connecting nodes. The data is loaded from a JSON file, and the chart renders as an SVG element that fills the viewport.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2b986511209a40459adb222c46220e7a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
