Here is my page:
http://analyticalpath.com/app/343200656/ . To load
the map you click the "worldwide map" button on the left, then click
"app popularity map".
You can see the code in the console when clicking that button. But
here is the code for reference:
<script type='text/javascript'>
$(document).ready(function(){
var map_data = new google.visualization.DataTable();
map_data.addColumn('string', 'Country');
map_data.addColumn('number', 'Rank');
map_data.addRows([["Finland",29],["New Zealand",34],["Canada",38],
["Ireland",41],["USA",49],["Australia",51],["Mexico",52],["Nicaragua",
54],["Norway",54],["Switzerland",54],["Netherlands",59],["UK",59],
["Germany",64],["Panama",65],["Denmark",67],["Belgium",67],
["Guatemala",70],["Austria",70],["Sweden",79],["Malta",84],["Slovakia",
84],["Latvia",85],["Paraguay",88],["El Salvador",89],["Spain",91],
["Hungary",93],["Cyprus",99],["France",103],["Greece",116],["Portugal",
116],["Poland",119],["Colombia",120],["Peru",121],["Lithuania",122],
["Italy",125],["Czech Republic",128],["Chile",134],["Ecuador",134],
["Slovenia",139],["Honduras",140],["Luxembourg",145],["Estonia",161],
["Bulgaria",163],["Argentina",164],["Venezuela",166],["Costa Rica",
176],["Romania",178],["Japan",189],["Dominican Republic",222],
["Bolivia",324],["Brazil",422]]);
var map_options = {colorAxis: {colors: ['#fee82f', '#000000']},
datalessRegionColor: '#000'};
var map_chart = new
google.visualization.GeoChart(document.getElementById('map_div'));
map_chart.draw(map_data, map_options);
});
</script>
It works in every browser except Firefox.
