{"version":"1.0","type":"rich","title":"Blank Canvas","description":"This visualization renders a hierarchical dataset of world regions and countries as a horizontal tree layout, with the root node (\"World\") anchored on the left and descendants extending rightward. The SVG output uses `d3.tree` and `d3.hierarchy` to compute node positions, while `d3.linkHorizontal` generates the curved connecting paths. Text labels, sized inversely to their depth, are placed at each node, and a `d3.zoom` handler enables panning and scaling of the entire canvas. The styling employs the Playfair Display font and teal strokes for the links.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2c1fab18ca3e438ca07b6abcbe1f2132?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
