Adding Columns of data on geochart

[Corbin]

I'm using the geoChart (US, resolution:metro), and have it working
with two columns of data (string(region), and number. I wanted to add
a third column of data (string), but it's not showing in the mouseover
tooltip like the others. The geochart example says the string (region)
is required, and there are two optional. I'm wondering why my 2nd
optional isn't showing, and is there really a 2 extra column limit to
each entry?

I think that's a typo in the documentation.  AFAIK, the geo charts only support 2 columns.

Indeed, that is a typo.

Note that you can change how  regions are named in the tooltip by setting the formatted value of the cell which holds the region name (dataTable.setFormattedValue(row, col, formattedValue)).

The same is true for your values. For example:

    function drawVisualization() {
      var data = new google.visualization.DataTable();
      data.addRows(6);
      data.addColumn('string', 'Country');
      data.addColumn('number', 'Popularity');
      data.setValue(0, 0, 'Germany');
      data.setValue(0, 1, 200);
      data.setValue(1, 0, 'United States');
      data.setValue(1, 1, 300);
      data.setValue(2, 0, 'Brazil');
      data.setValue(2, 1, 400);
      data.setValue(3, 0, 'Canada');
      data.setValue(3, 1, 500);
      data.setValue(4, 0, 'France');
      data.setValue(4, 1, 600);
      data.setValue(5, 0, 'RU');
      data.setValue(5, 1, 700);
      data.setFormattedValue(5, 0, "Russia");
      data.setFormattedValue(5, 1, "A lot");
      var geochart = new google.visualization.GeoChart(
          document.getElementById('visualization'));
      geochart.draw(data, {width: 556, height: 347});
    }
