{"version":"1.0","type":"rich","title":"Major U.S. Airports based on Departure Delay grouped by time of day(includes brushing)","description":"This visualization combines a U.S. map and a time histogram to show major airport departure delays grouped by time of day, with brushing to filter. The map uses `d3.geoAlbersUsa` projection and `d3.geoPath` to render state boundaries, with circles scaled by `d3.scaleSqrt` representing delay magnitude. The histogram, built with `d3.scaleLinear` and `d3.bin`, shows total delay per hour, and `d3.brushX` enables selecting time ranges to update the map. Data comes from a Flight Delay Analysis dataset, rendered in SVG.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d063796950974fdcb7588cf62f4372f6?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
