How the maps are drawn
National maps use the Albers equal-area conic projection, the standard for US maps because it preserves relative area. Alaska and Hawaii appear as insets; Alaska is shown at reduced scale. State maps use Web Mercator so they line up with the zoomable street map. Interactive maps are built with the open-source Leaflet library and load only when you interact with the page, which keeps every page fast.
