{"version":"1.0","type":"rich","title":"Node Link Trees","description":"This visualization displays a hierarchical tree of the world’s countries, organized by continent and region, as a node-link diagram. The layout uses a horizontal tree structure, with text labels at each node and connecting paths. Built with D3 v5, it uses the `tree` layout, `hierarchy` to process the JSON data, and `linkHorizontal` to draw the edges. The SVG rendering includes text with a white shadow for readability, and zoom functionality is implemented via the `zoom` event.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/61d0498661c4481e856e05f08e19c6f4?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
