{"version":"1.0","type":"rich","title":"Lars Test Graylog","description":"This interactive tree visualization maps a hierarchical structure of world regions and countries, rendered as an SVG with D3 v5. The layout uses `d3.tree` and `d3.hierarchy` to position nodes, with `d3.linkHorizontal` drawing curved connections. Users can pan and zoom through the diagram via `d3.zoom`, applied to a group element. Node labels display region and country names with font sizes decreasing by depth, sourced from a local JSON file. The visualization is styled with Roboto font and semi-transparent text shadows for readability.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3ac6ac3cd9d74a1bb1c34e47ddd89ae2?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
