This visualization uses a parallel coordinates plot to explore salary data for undergraduate majors across seven dimensions, including starting median salary, mid-career median salary, and various percentile breakpoints. Each polyline represents a major, rendered as an SVG path using d3.line, with axes scaled via d3.scalePoint and d3.scaleLinear. Hovering highlights a line in orange and displays a tooltip with the major’s name and all salary values. The data is loaded as CSV using d3.csv.
