{"version":"1.0","type":"rich","title":"Costa Rica","description":"This radial tree visualization displays a hierarchical World→Asia→subregion→country structure using an SVG rendering with d3.cluster layout. The view supports panning and zooming through d3.zoom, allowing exploration of the dense country hierarchy. Node labels at third depth levels orient tangentially around the circle, while shallower levels remain horizontal, with font sizes scaled by depth via d3.scaleSqrt. The data originates from data.json, mirroring Curran Kelleher’s World Countries Hierarchy block, with teal links drawn as cubic Bézier curves connecting parent-child nodes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/255f4512cc3f43eb8d0c735546be3d5d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
