Multiple Charts With GeoMap Render Issue

This issue is related to the following issue: 2772211

When rendering multiple charts onto a page, including a GeoMap, JS errors appear and no GeoMaps are rendered. If the other charts are removed from the JavaScript, the GeoMaps will render, however whenever a LineChart or BarChart is on the same page, errors like the following appear:

VM11267:2 Uncaught ReferenceError: gvjs_BM is not defined

This seems to have a very simple fix by changing:

  if (typeof google !== 'undefined') {
    google.load('visualization', '1', { callback: renderCharts });
  }

to this:

  if (typeof google !== 'undefined') {
    google.load('visualization', '1', { callback: renderCharts, packages: ['corechart'] });
  }

In the charts_google.js file, I have provided a patch for this issue.
