{"version":"1.0","type":"rich","title":"canvas","description":"A horizontal dendrogram visualizes the hierarchical structure of world countries, organized by continent and region. The tree layout is generated with `d3.tree` and rendered as an SVG using `d3.linkHorizontal`, with nodes labeled by country name. The chart supports zooming and panning via the `d3.zoom` event, which transforms the SVG group. Text labels are styled with a serif font and a white text-shadow for readability. The data is loaded from a JSON file containing the geographic hierarchy.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/75ae3077d7c841fbbd32a4c6d4d207f5?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
