        "\n# Compare PPI vs CAPPI\n\nThis example demonstrates how to create and compare PPI (Plan Position Indicator)\nand CAPPI (Constant Altitude Plan Position Indicator) plots using radar data.\n\nIn this example, we load sample radar data, create a CAPPI at 2,000 meters\nfor the 'reflectivity' field, and then plot both the PPI and CAPPI for comparison.\n"
