<good-map> is a simple custom element wrapper for Google Maps JavaScript API.

Include good-map.js somewhere on your page (async/defer are optional):

<script src="good-map.js" async defer></script>

Alternatively, use an HTML import to include good-map.html:

<link rel="import" href="good-map.html">

Create a <good-map> element anywhere on your page. Be sure to style the element with display: block and give it a height. You can also specify zoom, latitude, longitude, and map-options attributes:

<style>
good-map {
  display: block;
  height: 400px;
}
</style>

<good-map api-key="AIzaSyAQuo91bcoB-KwWXaANroTrzpNZRFcNJ1k"
    latitude="30"
    longitude="-100" zoom="2"
    map-options='{"mapTypeId": "satellite"}'></good-map>

Attributes on <good-map> are used for map initialization only and are not updated when the user interacts with the map. For interactive functionality, listen for the google-map-ready event and use goodMap.map or event.detail to access the underlying instance of google.maps.Map.
