This scatter plot shows daily weather conditions at Logan Airport versus flight delay duration, with each circle representing a day. Temperature appears on the y-axis, date on the x-axis, circle radius encodes departure delay, and color indicates precipitation, using a blue interpolated scale. The visualization uses D3 v5 with SVG rendering, employing `d3.scaleTime`, `d3.scaleLinear`, `d3.axisBottom`, and `d3.axisLeft`, while loading CSV data via `d3.csv`. Precipitation values below 0.1 appear as pale gray circles, and hover tooltips display the delay value.
