{"version":"1.0","type":"rich","title":"Fork of World Countries Tree","description":"This visualization shows the hierarchical structure of world countries, organized by continent and region, as a horizontal tree diagram. It uses D3 v5’s `tree` layout and `hierarchy` function to position the nodes, with `linkHorizontal` generating the curved connecting paths. The visualization supports zooming and panning via D3’s `zoom` behavior, while node labels are displayed with a font size that decreases with depth. The data comes from a local JSON file, and the SVG text elements include a white text-shadow for readability over the mint-green links.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2a56a5a7f28b4f8da77ae1ab6ad6d208?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
