{"version":"1.0","type":"rich","title":"Commercial Data Map","description":"This interactive visualization shows a hierarchical tree of commercial data, mapping a top-level \"Commercial\" category down through subcategories like \"Surface Access\" and individual leaf nodes such as \"Parking\" and country names. The network uses a tidy tree layout with horizontal links connecting parent and child nodes, with text labels sized proportionally to their depth in the hierarchy. Built with D3 v5, the code employs the `tree`, `hierarchy`, `linkHorizontal`, and `zoom` APIs, rendering an SVG that supports pan and zoom interactions via the `zoom` event.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4bd240e38b3243c4af85ee02b14e8bb8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
