{"version":"1.0","type":"rich","title":"Hello VizHub","description":"A hierarchical tree visualization displays the geographic structure of the World, Asia, and its subregions down to individual countries. The example renders a horizontal dendrogram using D3 v5, with the `d3.hierarchy` and `d3.tree` layouts computing node positions, while `d3.linkHorizontal` generates curved SVG paths for the links. Data is loaded from a local `data.json` file, and the SVG canvas is sized to the full viewport dimensions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/92a97def860e48be898aa1b4f46ce3c0?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
