{"version":"1.0","type":"rich","title":"The draft of radial chart","description":"This radial chart visualizes the average departure delay of USA airlines over time, with dates positioned around the circle’s circumference and delay values mapped outward from the center. The closed path connects daily data points using `d3.lineRadial` with `curveLinearClosed`, rendered in SVG within a React setup. Angle and radius scales are created with `d3.scaleLinear`, and the chart is centered by translating the coordinate system. Data comes from an external CSV file on airline on-time performance. Axes and tick labels are not yet implemented.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0142e40b10514c9f9f0f1c3636c6ca76?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
