{"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 tidy tree visualization, with the root at the left and leaves extending rightward. The tree layout positions nodes in a parent-child structure, and horizontal links connect them using `d3.linkHorizontal`. Labels display each region’s name, with font size scaling by depth and text anchors varying for leaf versus internal nodes. The visualization supports pan and zoom via `d3.zoom`, and loads the nested JSON data using `d3.json`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/769f603f6c4442ce9d258b807c86937a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
