Cette API se charge de manière asynchrone, pays par pays.
Google propose une autre API, qui se nomme Geomap (basée sur du Flash), et qui se charge plus rapidement que Geochart.
Elle est disponible à l'adresse :
https://developers.google.com/chart/interactive/docs/gallery/geomap?hl=fr
Voici un exemple de carte qui utilise l'API Geomap de Google :
http://temperatures-moyennes.fr/janvier.php
Et voici le code utilisé pour créer cette page :
<script type='text/javascript' src='https://www.google.com/jsapi'></script>
<script type='text/javascript'>
google.load('visualization', '1', {'packages': ['geomap']});
google.setOnLoadCallback(drawMap);
