{"version":"1.0","type":"rich","title":"Average Delay Time and Delay Reason for various carriers","description":"A stacked bar chart displays the average departure delay in minutes for each aircraft carrier, with bar segments colored by cancellation reason. Hovering over a segment reveals a tooltip with the exact delay reason and average delay time. Built with Vega-Lite and D3.js, the visualization aggregates the flight delay dataset by carrier and cancellation reason using the `groupby` and `average` transforms. The chart is rendered via the Vega-Lite API, with data loaded asynchronously from a CSV file using D3's `csv` function.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/60cc4bfb0e774b46a8f4f1f1f85f61fc?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
