[Javascript] Get Started with LeafletJS Mapping

Leaflet makes creating maps in the browser dead simple. With some HTML and 3 lines of JavaScript, we can quickly have a map displaying

// create a map in the "map" div, set the view to a given place and zoom

var map = L.map('map').setView([51.505, -0.09], 13);

// add an OpenStreetMap tile layer

L.tileLayer('http://{s}.tile.osm.org/{z}/{x}/{y}.png', {

    attribution: '&copy; <a href="http://osm.org/copyright">OpenStreetMap</a> contributors'

}).addTo(map);

// add a marker in the given location, attach some popup content to it and open the popup

L.marker([51.5, -0.09]).addTo(map)

    .bindPopup('A pretty CSS3 popup. <br> Easily customizable.')

    .openPopup();

var circle = L.circle([51.508, -0.11], 500, {

    color: 'red',

    fillColor: '#f03',

    fillOpacity: 0.5

}).addTo(map);

var polygon = L.polygon([

    [51.509, -0.08],

    [51.503, -0.06],

    [51.51, -0.047]

]).addTo(map);
