{"version":"1.0","type":"rich","title":"[test] On-time performance of top-5 busiest airports in USA","description":"This radial chart shows the on-time performance of the five busiest US airports, with each colored ring representing an airport’s average departure delay over time. The chart uses D3’s `scaleTime` for the angular axis and `scaleLinear` for the radial axis, with `lineRadial` and `curveLinearClosed` to draw the closed paths. An interactive color legend, built in React, filters and highlights each airport’s trajectory on hover. Data is loaded from a CSV file using D3’s `csv` parsing.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/34ac6d92dd4646f3bb9b5d399171791f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
