{"version":"1.0","type":"rich","title":"Monthly Passenger Count for Year 2019","description":"This grouped bar chart shows monthly passenger counts for domestic and international flights at San Francisco airport in 2019. The visualization uses d3.nest() to aggregate and group the CSV data by month and flight type, with d3.scaleBand for the x-axis and d3.scaleLinear for the y-axis. Bars are rendered as SVG rects with color encoding via d3.scaleOrdinal, and axes use d3.axisBottom and d3.axisLeft with custom time and count formatters. Data comes from DataSF’s Air Traffic Passenger Statistics dataset.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a2b2b2d7ad1848f4aa4d215890934544?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
