This interactive scatter plot visualizes daily temperature readings from Logan Airport weather data collected between 2016 and 2018. Built with React and D3 v5, the visualization renders an SVG chart where users can switch between TMAX and TMIN values for the y-axis using ReactDropdown menus, while the x-axis displays dates scaled with d3.scaleTime. The d3.csv loading pipeline parses the raw data, and d3.extent determines the domain for both linear and time scales. Circle marks include native SVG title tooltips showing formatted dates.
