+[Leaflet.js](https://leafletjs.com/)でMapboxのタイルを用いて地図を表示してみます:
+
+<div id="mapid"></div>
+
+<script>
+  var mymap = L.map('mapid').setView([35.7142, 139.7774], 13)
+
+  L.tileLayer('https://api.tiles.mapbox.com/v4/{id}/{z}/{x}/{y}.png?access_token=pk.eyJ1Ijoia2F6dTYzNCIsImEiOiJjanU4OHg0YjIyMjcxNDNsb2dnM2k5bHhqIn0.dsjWTh-G_TcJ9bOGWLvT2Q', {

+    maxZoom: 18,
+    id: 'mapbox.streets',
+    accessToken: 'pk.eyJ1Ijoia2F6dTYzNCIsImEiOiJjanU4OHg0YjIyMjcxNDNsb2dnM2k5bHhqIn0.dsjWTh-G_TcJ9bOGWLvT2Q'
+  }).addTo(mymap);
+
+  var marker = L.marker([35.7142, 139.7774]).addTo(mymap);
+  marker.bindPopup("<b>Hello world!</b><br>I am a popup.").openPopup();
+</script>
+
+## コード
+こんな感じになります:
+
+```
+<div id="mapid"></div>
+
+<script>
+  var mymap = L.map('mapid').setView([35.7142, 139.7774], 13)
+
