{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"This visualization displays the hierarchical structure of world regions and countries as a horizontal tree layout, using the country names themselves as the visual elements. The D3.js v5 code loads country data from a JSON file, applies the `tree` layout, and renders the hierarchy via SVG paths for links and text nodes whose font size scales with depth. The visualization supports pan and zoom interactions through the `zoom` function, making it easy to explore the nested geographic groupings.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/441554361a8a4a419d5964024d8bdcf2?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
