{"version":"1.0","type":"rich","title":"Logan Airport Weather vs Delay","description":"Logan Airport weather delays for 2016 are shown as a radial ring chart, with each day’s weather delay represented by an arc extending outward from the center. Arc color indicates the presence of adverse weather codes, using red for days with weather events and blue for clear days. The visualization uses D3 v5 with `d3.arc` and `d3.scaleLinear` to map dates to angles and delay magnitudes to radii. Interactive, transparent overlay arcs handle mouseover events to display exact dates and delay values via a tooltip, while a crosshair line follows the cursor.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/011d1bb13d484d25be5f47e528dde9a8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
