This visualization displays the total number of crimes across U.S. cities using a choropleth map layered with circular points. The map renders U.S. states as geographic shapes and overlays city-level crime totals as circles, colored by value and showing city names on hover. It is built with Vega-Lite and the Vega-Lite API, using the `vl.markGeoshape` and `vl.markCircle` layers, an Albers USA projection, and TopoJSON data for state boundaries. Crime data originates from the U.S. Metro Areas Violent Crime Rates dataset, loaded via D3’s `csv` parser.
