⚠️ Prices are by state, not county — no open county-level gas-price data exists. EIA publishes state-specific prices for 7 states (CO, FL, MN, NY, OH, TX, WA); other states show their PADD regional price (per-state tooltip says which). Producing areas coloured oil/gas/mixed by predominant product — a documented characterization; EIA's polygons carry no product field.
