Google Charts

Visualization: Map


The Google Map Chart displays a map using the Google Maps API. Data values are displayed as markers on the map. Data values can be coordinates (lat-long pairs) or addresses. The map will be scaled so that it includes all the identified points.

If you want your maps to be line drawings rather than satellite imagery, use a geochart instead.

Named Locations

You can identify the places to put markers by name, as shown below in this map of the top ten countries by population.

When the user selects one of the markers, a tooltip with the name and population of the country is displayed, because we used the showTip option. Here's the full HTML:

  <script type="text/javascript" src=""></script>
    google.load('visualization', '1', { 'packages': ['map'] });

    function drawMap() {
      var data = google.visualization.arrayToDataTable([
        ['Country', 'Population'],
        ['China', 'China: 1,363,800,000'],
        ['India', 'India: 1,242,620,000'],
        ['US', 'US: 317,842,000'],
        ['Indonesia', 'Indonesia: 247,424,598'],
        ['Brazil', 'Brazil: 201,032,714'],
        ['Pakistan', 'Pakistan: 186,134,000'],
        ['Nigeria', 'Nigeria: 173,615,000'],
        ['Bangladesh', 'Bangladesh: 152,518,015'],
        ['Russia', 'Russia: 146,019,512'],
        ['Japan', 'Japan: 127,120,000']

    var options = { showTip: true };

    var map = new google.visualization.Map(document.getElementById('chart_div'));

    map.draw(data, options);
    <div id="chart_div"></div>

Geocoded Locations

You can also specify locations by latitude and longitude, which loads faster than named locations:

The above chart identifies four locations by latitude and longitude.

  var data = google.visualization.arrayToDataTable([
    ['Lat', 'Long', 'Name'],
    [37.4232, -122.0853, 'Work'],
    [37.4289, -122.1697, 'University'],
    [37.6153, -122.3900, 'Airport'],
    [37.4422, -122.1731, 'Shopping']
    <script type="text/javascript" src=""></script>
    <script type="text/javascript">
      google.load("visualization", "1", {packages:["map"]});
      function drawChart() {
        var data = google.visualization.arrayToDataTable([
          ['Lat', 'Long', 'Name'],
          [37.4232, -122.0853, 'Work'],
          [37.4289, -122.1697, 'University'],
          [37.6153, -122.3900, 'Airport'],
          [37.4422, -122.1731, 'Shopping']

        var map = new google.visualization.Map(document.getElementById('map_div'));
        map.draw(data, {showTip: true});


    <div id="map_div" style="width: 400px; height: 300px"></div>


The google.load package name is "map".

  google.load("visualization", "1", {packages: ["map"]});

The visualization's class name is google.visualization.Map.

  var visualization = new google.visualization.Map(container);

Data Format

Two alternative data formats are supported:

  1. Lat-Long pairs - The first two columns should be numbers designating the latitude and longitude, respectively. An optional third column holds a string that describes the location specified in the first two columns.
  2. String address - The first column should be a string that contains an address. This address should be as complete as you can make it. An optional second column holds a string that describes the location in the first column. String addresses load more slowly, especially when you have more than 10 addresses.

Note: The Lat-Long pairs option loads maps much faster, especially with large data. We recommend that you use this option for large data sets. Please visit Google Maps API to find out how to transform your addresses to lat-long points. The map can display a maximum of 400 entries; if your data holds more than 400 rows, only the first 400 will be shown.

Configuration Options

Name Type Default Description
enableScrollWheel boolean false If set to true, enables zooming in and out using the mouse scroll wheel.
showTip boolean false If set to true, shows the location description as a tooltip when the mouse is positioned above a point marker.
showLine boolean false If set to true, shows a Google Maps polyline through all the points.
lineColor string default color If showLine is true, defines the line color. For example: '#800000'.
lineWidth number 10 If showLine is true, defines the line width (in pixels).
mapType string 'hybrid' The type of map to show. Possible values are 'normal', 'terrain', 'satellite' or 'hybrid'.
useMapTypeControl boolean false Show a map type selector that enables the viewer to switch between [map, satellite, hybrid, terrain]. When useMapTypeControl is false (default) no selector is presented and the type is determined by the mapType option.
zoomLevel number automatic An integer indicating the initial zoom level of the map, where 0 is completely zoomed out (whole world) and 19 is the maximum zoom level. (See "Zoom Levels" in the Google Maps API.)


Method Return Type Description
draw(data, options) none Draws the map.
getSelection() Array of selection elements Standard getSelection() implementation. Selection elements are all row elements. Can return more than one selected row.
setSelection(selection) none Standard setSelection() implementation. Treats every selection entry as a row selection. Supports selection of multiple rows.


Name Description Properties
error Fired when an error occurs when attempting to render the chart. id, message
select Standard select event None
