{"version":"1.0","type":"rich","title":"[test] On-time performance of top-5 busiest airports in USA","description":"A radial line chart shows the average departure delay for the five busiest US airports across months, with each airport’s performance traced as a colored, closed loop around a circular timeline. A legend indicates airport names and colors; hovering over a legend entry highlights that airport’s trace while dimming the others. The visualization is built with React and rendered as an SVG, using D3 v5 functions such as `scaleTime` and `scaleLinear` for the angle and radial axes, `pointRadial` to position ticks, `curveLinearClosed` to close each path, and a custom `ColorLegend` component. Data is loaded from a CSV file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/14a6a324b69548e59c92193de2f172d5?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
