{"version":"1.0","type":"rich","title":"Hotel Reservation Tree","description":"This visualization shows the total lead time for each reserved room type across Resort hotels worldwide, organized hierarchically by hotel and country. The data comes from a World Bank CSV file and is processed using D3 v5’s `nest` and `tree` functions to build a stratified tree layout. Each leaf node is a colored circle, where color maps the aggregate lead-time value via `scaleLinear` from green to red, and horizontal links are drawn with `linkHorizontal`. Text labels display hotel, country, and room type names, with font sizes adjusted by depth. The SVG canvas supports interactive zooming through the `zoom` event.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/aac09a91a1bb4cf3a452d671b9b81e35?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
