{"version":"1.0","type":"rich","title":"[test] On-time performance of top-5 busiest airports in USA","description":"This radial chart compares on-time performance across the five busiest US airports using D3 v5 and React. Monthly average departure delays are plotted along a circular time axis, with each airport shown as a distinct colored line. The visualization includes an interactive color legend that highlights a selected airport while fading the others, and angle tick marks label the months. Data comes from a CSV file loaded via d3.csv. The code uses d3.lineRadial with curveLinearClosed, d3.scaleTime, d3.scaleOrdinal, and d3.pointRadial for positioning.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0eec5b77f1204c5faf721b62054e9634?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
