{"version":"1.0","type":"rich","title":"World Countries Tree","description":"This visualization displays the hierarchy of world countries organized by continent and subregion as a tree structure. The hierarchical data, which shows the path from \"World\" down to individual countries like Afghanistan and India, is loaded from a JSON file. The SVG rendering uses D3 v5 to create the visualization, with the page dimensions determining the width and height of the SVG canvas. The code sets up a blank rectangle as the background but does not yet implement the tree layout or node rendering, only loading and logging the data.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/62e0a7ead6ac42eca4f68c2b551a9a27?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
