Placard.js

A dead simple interface for creating Google Maps with multiple points.

Usage

Begin by including the Maps API and Placard JavaScript files:

<script src="//maps.googleapis.com/maps/api/js?key=API_KEY"></script>
<script src="placard.js"></script>

Create an object containing the points you want to add to your map. The only required properties are lat and lng. Use latlng.me if you need help.

var locations = [
  {
    lat: 39.73703,
    lng: -104.97280
  },
  {
    lat: 39.76463,
    lng: -105.00401
  },
  {
    lat: 39.75046,
    lng: -104.99954
  },
  {
    lat: 39.74414,
    lng: -104.98984
  },
  {
    lat: 39.76112,
    lng: -104.98172
  }
];

Next, create a new map using Placard.Map:

var map = new Placard.Map('canvas', {
  center: {
    lat: 39.73932,
    lng: -104.98480
  },
  zoom: 13
});

Finally, add your locations to the map:

locations.forEach(function(location) {
  map.addPoint(location);
});
