{"version":"1.0","type":"rich","title":"Art Tree","description":"This example shows a horizontal tree diagram of world regions and countries, using a hierarchical dataset that groups nations by continent and subregion. The code builds the layout with `d3.tree()` and `d3.hierarchy()`, then renders the parent-child connections as curved SVG paths via `d3.linkHorizontal()`. Each node represents a geographic entity, with the root labeled “World” and branches extending through continents like Asia. The visualization responds to the full browser viewport, with the SVG sized to the window dimensions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4f3ab3ae049547b595493a44c8dc87a4?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
