Shows a Python workflow that turns tabular police records from open police data into spatial data with GeoPandas, converts a column to WKT/geometries and plots maps with contextily or folium. Works for city-level summaries across most major cities and towns in Virginia, but individual incident locations are missing so no point-level analysis is possible. Demonstrates basemaps from OpenStreetMap, how they’re added, and the practical limitation of the input data.
