Two choropleth maps of U.S. states display minimum wage values from a CSV dataset, with a legend that lists selected states and color-coded circles. Clicking states toggles their inclusion, adding them to an ordinal color scale and generating corresponding time-series line graphs lower on the page. The visualization uses d3.geoPath and a geoTransform projection for the maps, d3.line with curveBasis for the graph paths, and d3.scaleOrdinal with schemeSpectral for coloring.
