This choropleth map visualizes earthquake counts across U.S. states using a logarithmic color scale from the OrRd scheme. It shows total earthquakes per state, with darker shades representing higher counts and hover effects highlighting individual states. The visualization uses D3 v5 with d3.geoAlbersUsa projection and d3.geoPath to render TopoJSON state boundaries from the states-10m dataset. State earthquake data comes from a CSV file, and a custom tooltip displays state name, region, and earthquake count on hover.
