google visualization - Can Region GeoChart be displayed for different states of different countries and can custom text be displayed on the Region GeoChart?

Question

We are using Google Region GeoChart to implement chart similar to Excel Map Chart.

1. Requirement is to display states of more than one country on the Region GeoChart. Tried to use region property set to world but this does not work.

    function drawRegionsMap() {
            var objChart = [
                      ['State', 'Popularity'],
                      ['Maharashtra', 200],
                      ['Goa', 300],
                      ['Kerala', 400],
                      ['Alabama', 500],
                      ['Colorado', 600],
                      ['Idaho', 700]
            ];
    var data = google.visualization.arrayToDataTable(objChart);
            var options = {
                region: 'world',
                displayMode: 'regions',
                resolution: 'provinces',
                colorAxis: { colors: ['#e7711c', '#4374e0'] }
            };
            var chart = new google.visualization.GeoChart(document.getElementById('dvMapChartContainer'));
            chart.draw(data, options);
        }
   

2. Is it possible to display text like shown below on the Region GeoChart? If yes, then is there a way that be done?
