This visualization combines a scatter plot with a ring chart to explore relationships between weather conditions and flight delays at Logan Airport. The scatter plot maps daily maximum temperature on the y-axis against date on the x-axis, with circle size representing departure delay magnitude and color indicating precipitation levels. The ring chart presents the same delay data as radial bars arranged around a circle. Both charts use d3.csv to load the dataset, with d3.scaleLinear, d3.scaleTime, and d3.axisBottom/Left for the scatter plot, while the ring chart employs d3.rect elements rotated via d3.scaleLinear.
