This visualization compares minimum wage data across U.S. states with two choropleth maps (one for a current year, one for 2018) and a line graph of trends over time. Users click states to select them, which highlights them on both maps and adds their wage trajectories to the graph using d3.line and d3.curveBasis. The maps use d3.geoPath with a custom scaler and a topojson feature collection. A d3.scaleOrdinal color legend with d3.schemeSpectral maps each selected state to a unique line color.
