This interactive bar chart displays earnings and labor data for 16 graduate program categories, sourced from FiveThirtyEight. A dropdown menu lets the viewer select which metric to display on the y-axis. The visualization uses d3.scaleLinear and d3.scaleBand for scales, with d3.axisLeft and d3.axisBottom for axes. The bars animate via a d3.transition on rect attributes, while the menu is built with a custom dropdownMenu module.
