Your javascript is missing the closing braces and parenthesis for the AJAX
call and the drawMarkersMap function:
function drawMarkersMap() {
$.ajax({
url: "getData.json",
dataType:"json",
success: function (json) {
// Create our data table out of JSON data loaded from server.
var data = new google.visualization.DataTable(jsonData);
var options = {
region: 'US',
displayMode: 'markers',
colorAxis: {colors: ['green', 'blue']}
};
var chart = new
google.visualization.GeoChart(document.getElementById('visualization'));
chart.draw(data, options);
} // <-- the ";" that was here does not belong
}); // <-- missing this
} // <-- and this
Try that and see if it works.
