This fork of the Simple Scatter Plot shows a dual-axis chart of Seattle weather data, displaying precipitation as blue bars and maximum temperature as a red line, with separate left and right Y-axis scales. It uses d3.csv to load the dataset, then d3.scaleTime and d3.scaleLinear to create the scales, with d3.axisLeft, d3.axisRight, and d3.axisBottom for the axes. The chart renders gridlines and includes interactive accessibility attributes, with the six-month slice of data displayed across the responsive width of its container.
