Using a geochart with OOcharts

geochart.js

oo.load(function(){
  
  var regionQuery = new oo.Query('PROFILE ID', "30d");
  
  //Add metrics, dimensions, and filter for region
  regionQuery.addMetric('ga:visits');
  regionQuery.addDimension('ga:metro');
  regionQuery.setFilter('ga:region==California');
  
  regionQuery.execute(function(data){
    var _rows = data.rows;
     
    //remove first row (not set row)
    _rows.shift();
      
    // Add column headers
    _rows.unshift(['State', 'Visits']);
     
    var dt = google.visualization.arrayToDataTable(_rows);
                        
    var _ele = document.getElementById('regionGeo');
                        
    var regionGeo = new google.visualization.GeoChart(_ele);
                        
    regionGeo.draw(dt, {
      backgroundColor : 'transparent',
      region : 'US-CA',
