{"version":"1.0","type":"rich","title":"Major U.S. Airports based on Departure Delay grouped by time of day(includes Pan & Zoom, Hover highlighting of state, Tooltips & Brushing with React Performance Optimization)","description":"This visualization combines a map of major U.S. airports with a histogram of flight departure delays, grouped by hour of the day. Airports appear as semi-transparent circles scaled by departure delay, with hover tooltips showing city and state, and states highlighting on hover. The map supports pan and zoom via d3.zoom, while the histogram uses d3.brushX to filter the map data. React useMemo optimizes rendering, and the map uses d3.geoAlbersUsa with U.S. state boundaries from us-atlas. Data comes from a CSV of flight delays.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/84bdfe722e5c485b833f798327f37822?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
