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.
