cool module, had no problems generating line charts, etc.
I would like the show a GeoChart but it doesn't seem to work.
I have 2 fields in my view, "Country" and "Members". I can show them as LineChart or BarChart. Country is the 2 digit country code.
When I change to "GeoChart" I get a js error:

if (element) {
            chart[settings.chart[chartId]] = new google.visualization[settings.chart[chartId].chartType](element);
Uncaught TypeError: undefined is not a function

Right, there is no support right now for GeoChart, and it's needs to be take care of.

Is there a plan to incorporate GeoChart in the future? Does anyone know of another module that supports GeoChart?

Jayson according to my research, there is no Drupal module that supports geochart. I will be keeping an eye on this thread to see if that changes. :-)

Hey koppie, here's a thread for Views Dataviz that gives a way of doing it for that module. I'm going to try it myself.

Committed to DEV.
It should be possible now to use the Geo Chart. For example:

$settings['chart']['chartOne'] = array(
    'header' => array("Germany", "United States", "Brazil", "Canada", "France", "RU" ),
    'rows' => array(array('200', '300', '400', '500', '600', '700')),
    'columns' => array("Population"),
    'chartType' => 'GeoChart',
    'containerId' =>  'content',
    'options' => array(
      'forceIFrame' => FALSE,
      'title' => 'Geo Chart',
      'width' => 800,
      'height' => 400,
      'backgroundColor' => 'B1E7F2'
  //Draw it.
  $ret = draw_chart($settings);

Please test and review, Thanks.
