{"version":"1.0","type":"rich","title":"Radial","description":"A radial chart displays average flight delays for US airlines across months, with two overlaid paths comparing departure and arrival delays. The visualization uses React with D3 v5’s `lineRadial` and `curveLinearClosed` to create circular lines, while `scaleTime` maps dates to angles and `scaleLinear` maps delay values to radial distances. An ordinal color scale distinguishes the two delay types, and a custom SVG legend explains the color encoding. Data comes from a CSV file of airline performance metrics loaded via `d3.csv`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/57778b28b2684bdc812cb6f65b351516?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
