State level data of India not showing in google geochart

[Subhabrata Bose]

Hi

   I am loading Map of India using Geochart. On click of any Indian State I want to load the Image of that state(eg Maharashtra), but i am getting the Message - Requested map does not exist. 

   

My Code:

var data = new google.visualization.DataTable();

data.addColumn('string',  'State', 'State');

        data.addColumn('number', 'Area Percentage', 'Area Percentage');

data.addColumn({type:'string', role:'tooltip', 'p': {'html': true}});

data.addRows([            

['Maharashtra',  11, 'Balance: 1342720534.59997, fffff: 1342720544.59997'],

['Kerala',  1, 'Balance: 1342720534.59997, fffff: 1342720544.59997'],

['Punjab', 10, 'Balance: 1342720534.59997, fffff: 1342720544.59997'],

['Rajasthan',  10, 'Balance: 1342720534.59997, fffff: 1342720544.59997'],

['Uttar Pradesh',  7, 'Balance: 1342720534.59997, fffff: 1342720544.59997']

]);

var val = [0, 5, 10, 20, 30, 50];

var options = {

tooltip: {isHtml: true},

backgroundColor: '#81d4fa',

region: 'IN',

domain: 'IN',

displayMode: 'markers', //auto is zonecolor

datalessRegionColor: '#a6a6a6',

colorAxis: {colors: ['red', 'yellow', 'violet', 'pink', 'blue', 'green'], values: val1}

};

var chart = new google.visualization.GeoChart(document.getElementById('mapDiv'));

chart.draw(data, options);

google.visualization.events.addListener(chart4, 'regionClick', function(eventData) {

var selectedItem = eventData.region;

if (selectedItem) {

var data = new google.visualization.DataTable();

data.addColumn('string',  'City', 'City');

data.addColumn('number', 'perc', 'perc');

data.addColumn({type:'string', role:'tooltip', 'p': {'html': true}});

data.addRows([            

['Amravati',  11, 'Balance: 1342720534.59997, fffff: 1342720544.59997'],

['Aurangabad',  1, 'Balance: 1342720534.59997, fffff: 1342720544.59997'],

['Jalna', 10, 'Balance: 1342720534.59997, fffff: 1342720544.59997'],

['Kolhapur',  10, 'Balance: 1342720534.59997, fffff: 1342720544.59997'],

['Nagpur',  7, 'Balance: 1342720534.59997, fffff: 1342720544.59997']

]);

var val = [0, 3, 10, 25, 35, 55];

options['region'] = selectedItem;

options['resolution'] = 'metros';

options['displayMode'] = 'markers';

options['colorAxis'] = {colors: ['red', 'yellow', 'violet', 'pink', 'blue', 'green'], values: val};

chart.draw(data, options);

}

});

Thank you for the help in advance.
