Create a `circle` with a radius in meters

auto circle = xlf::circle_generator()
    .location({50, 354})
    .radius(50000)

    .finalize();

Create a `circle_marker` with a radius in pixels



In [ ]:

    
auto circle_marker = xlf::circle_marker_generator()
    .location({55, 360})
    .radius(50)
    .color("red")

Create a `rectangle`



In [ ]:

    
auto rectangle = xlf::rectangle_generator()
    .bounds({{{52, 354}, {53, 360}}})
    .finalize();

map.add_layer(rectangle);
