Example¶

#include <fstream>

#include "xleaflet/xmap.hpp"

auto black_and_white = xlf::basemap({"OpenStreetMap", "BlackAndWhite"});

auto map = xlf::map::initialize()
    .layers({black_and_white})
    .center({34.6252978589571, -77.34580993652344})
    .zoom(10)
    .finalize();

// Load a local file
std::ifstream file("geo.json");
xeus::xjson geo_data;
file >> geo_data;

auto geo_json = xlf::geo_json::initialize()
    .data(geo_data)
    .finalize();
map.add_layer(geo_json);
