{"version":"1.0","type":"rich","title":"Fork of POI Category Tree","description":"This example visualizes the hierarchy of ArcGIS-supported point-of-interest categories, with roughly 300 child categories grouped under 10 major parent categories. The tree is laid out horizontally using `d3.tree()` and `d3.hierarchy()`, with nodes positioned by size and links drawn via `d3.linkHorizontal()`. The SVG rendering is zoomable and pannable through `d3.zoom()`, and labels are angled at each leaf for readability. Data is loaded from a CSV file using `d3.csv`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8e7c133229924c549777cf1802b6d9af?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
