{"version":"1.0","type":"rich","title":"Logan Weather data with Interactive Color Legend","description":"This visualization presents daily weather delay data from Logan Airport in 2016 as an interactive ring chart. Each arc segment represents a day, with the radius encoding delay duration and color distinguishing weather severity levels using a categorical scale. An interactive color legend allows users to hover over severity categories, fading non-matching arcs. Built with React and D3 v5, the visualization uses `scaleTime` for angular positioning, `scaleLinear` for radial encoding, and `d3.arc()` for path generation.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7b3a90296fd644bc9f1e74fa21d76501?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
