{"version":"1.0","type":"rich","title":"World Countries Tree","description":"This interactive visualization displays the hierarchical structure of world countries, organized by continent and subregion. Built with D3.js v5, it renders a horizontal tree diagram using SVG, where each node represents a geographical region or country. The visualization uses D3's tree layout algorithm with hierarchical data, and implements zoom functionality through the `d3.zoom` API. Text labels are styled with the Playfair Display font, and links are colored with a distinct teal stroke. The data originates from a JSON file containing nested country and region classifications.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f9277bcf61e3420cbb6ea0fb598c5693?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
