from route_planner import RoutePlanner # Initialize the planner planner = RoutePlanner() # Add some points to the map planner.add_point("New York", 40.7128, -74.0060) planner.add_point("Chicago", 41.8781, -87.6298) planner.add_point("Los Angeles", 34.0522, -118.2437) # Plan the route from New York to Los Angeles route = planner.plan_route("New York", "Los Angeles") print(route)In this example, we initialize the RoutePlanner object, add three points to the map (New York, Chicago, and Los Angeles), and then plan a route from New York to Los Angeles. The `plan_route` method returns a list of points on the route from the start point to the end point. The RoutePlanner package library is not clear from this brief example, but it likely includes map and routing APIs or integrations with such services.
