{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"This example renders a hierarchical dataset of world regions and countries as a horizontal tree, using D3.js v5. The visualization groups countries under regions such as Southern Asia and Western Asia, with text labels sized by depth. The code builds the layout with `d3.tree` and `d3.hierarchy`, draws curved links via `d3.linkHorizontal`, and applies zooming through `d3.zoom`. Data loads from a JSON file, and SVG elements are styled with a custom font and blue stroke.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f58aff6c4e7f4f9fbb2387cb09ceb2b1?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
