This scatter plot visualizes earnings and labor force data for college majors, sourced from FiveThirtyEight. It uses d3.scalePoint and d3.scaleLinear for axes, with d3.scaleOrdinal for color encoding by major category and a custom stem legend for STEM classification. A dropdown menu, built with d3, lets users select different y-axis metrics, while clicking legend items filters and highlights points. SVG circles animate with d3.transition, and tooltips display major names, all rendered via d3-selection.
