GeoCharts: define text that appears when hovering country

[UnknownInnocent]

Hello I just started using GeoCharts and I have a question that wasn't answered for me with the information given.

I have following code:

 var data = google.visualization.arrayToDataTable([

          ['Country', ''],

          ['India', 2],

          ['Australia', 10],

          ['Germany', 1],

          ['United States', 2],

          ['Brazil', 2],

          ['Canada', 3],

          ['France', 2],

          ['RU', 2]

        ]);

    var options = {

      backgroundColor: '#17263c',

      datalessRegionColor: '#242f3e',

      legend: 'none',

      colors: ['#00853f', 'black', '#e31b23']

    };

If I now hover a country, I get a box with two rows:

1. row: the county's name

2. row: the number

now I would like to define a custom text to show in the second line and use the numbers just to tell what color the country should have.

example for output I'd like to have:

1. row: the county's name

2. row: homecountry
