{"version":"1.0","type":"rich","title":"Hotel checkin and checkout by Cities","description":"A world map displays simulated hotel check-ins and checkouts across multiple cities, with circles sized by guest counts and colored to indicate business versus leisure travel. A time-brushing histogram below filters the map data by date range. Built with React and D3, the visualization uses `d3.geoNaturalEarth1`, `d3.geoPath`, and `d3.scaleSqrt` for mapping and scaling, while `d3.brushX` enables interactive temporal selection. Data is generated procedurally, simulating guest arrivals and departures over 20 days.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/58d5017694394e749f2590790b293a96?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
