JQVMap

This project is a heavily modified version of jVectorMap. I chose to start fresh rather than fork their project as my intentions were to take it in such a different direction that it would become incompatibale with the original source, rendering it near impossible to merge our projects together without extreme complications.

jQuery Vector Map

To get started, all you need to do is include the JavaScript and CSS files for the map you want to load. Here is a sample HTML page for loading the World Map with default settings:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
  <head>
    <title>JQVMap - World Map</title>

    <link href="../jqvmap/jqvmap.css" media="screen" rel="stylesheet" type="text/css" />

    <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js" type="text/javascript"></script>
    <script src="../jqvmap/jquery.vmap.js" type="text/javascript"></script>
    <script src="../jqvmap/maps/jquery.vmap.world.js" type="text/javascript"></script>

	<script type="text/javascript">
	jQuery(document).ready(function() {
		jQuery('#vmap').vectorMap({ map: 'world_en' });
	});
	</script>
  </head>
  <body>
    <div id="vmap" style="width: 600px; height: 400px;"></div>
  </body>
</html>

Making it Pretty

While initializing a map you can provide parameters to change its look and feel.

jQuery('#vmap').vectorMap(
{
    map: 'world_en',
    backgroundColor: '#a5bfdd',
    borderColor: '#818181',
    borderOpacity: 0.25,
    borderWidth: 1,
    color: '#f4f3f0',
    enableZoom: true,
    hoverColor: '#c9dfaf',
    hoverOpacity: null,
    normalizeFunction: 'linear',
    scaleColors: ['#b6d6ff', '#005ace'],
    selectedColor: '#c9dfaf',
    selectedRegion: null,
    showTooltip: true,
    onRegionClick: function(element, code, region)
    {
        var message = 'You clicked "'
            + region 
            + '" which has the code: '
            + code.toUpperCase();
         
        alert(message);
    }
});

Configuration Settings

map 'world_en'

Map you want to load. Must include the javascript file with the name of the map you want. Available maps with this library are world_en, usa_en, europe_en and germany_en

backgroundColor '#a5bfdd'

Background color of map container in any CSS compatible format.

borderColor '#818181'

Border Color to use to outline map objects

borderOpacity 0.5

Border Opacity to use to outline map objects ( use anything from 0-1, e.g. 0.5, defaults to 0.25 )

borderWidth 3

Border Width to use to outline map objects ( defaults to 1 )

color '#f4f3f0'

Color of map regions.

colors

Colors of individual map regions. Keys of the colors objects are country codes according to ISO 3166-1 alpha-2 standard. Keys of colors must be in lower case.

enableZoom boolean

Whether to Enable Map Zoom ( true or false, defaults to true)

hoverColor '#c9dfaf'

Color of the region when mouse pointer is over it.

hoverOpacity 0.5

Opacity of the region when mouse pointer is over it.

normalizeFunction 'linear'

This function can be used to improve results of visualizations for data with non-linear nature. Function gets raw value as the first parameter and should return value which will be used in calculations of color, with which particular region will be painted.

scaleColors ['#b6d6ff', '#005ace']

This option defines colors, with which regions will be painted when you set option values. Array scaleColors can have more then two elements. Elements should be strings representing colors in RGB hex format.

selectedRegion 'mo'

This is the Region that you are looking to have preselected (two letter ISO code, defaults to null )

showTooltip boolean

Whether to show Tooltips on Mouseover ( true or false, defaults to true)

onLabelShow function(event, label, code)

Callback function which will be called before label is shown. Label DOM object and country code will be passed to the callback as arguments.

onRegionOver function(event, code, region)

Callback function which will be called when the mouse cursor enters the region path. Country code will be passed to the callback as argument.

onRegionOut function(event, code, region)

Callback function which will be called when the mouse cursor leaves the region path. Country code will be passed to the callback as argument.

onRegionClick function(event, code, region)

Callback function which will be called when the user clicks the region path. Country code will be passed to the callback as argument. This callback may be called while the user is moving the map. If you need to distinguish between a "real" click and a click resulting from moving the map, you can inspect $(event.currentTarget).data('mapObject').isMoving.

Dynamic Updating

Most of the options can be changed after initialization using the following code:

jQuery('#vmap').vectorMap('set', 'colors', {us: '#0000ff'});

Instead of colors can be used any parameter except callbacks. Callbacks can be added and deleted using standard jQuery patterns of working with events. You can define callback function when you initialize JQVMap:

jQuery('#vmap').vectorMap(
{
    onLabelShow: function(event, label, code)
    {
 
    },
    onRegionOver: function(event, code, region)
    {
 
    },
    onRegionOut: function(event, code, region)
    {
 
    },
    onRegionClick: function(event, code, region)
    {
 
    }
});

Or later using standard jQuery mechanism:

jQuery('#vmap').bind('labelShow.jqvmap', 
    function(event, label, code)
    {
 
    }
);
jQuery('#vmap').bind('regionMouseOver.jqvmap', 
    function(event, code, region)
    {
 
    }
);
jQuery('#vmap').bind('regionMouseOut.jqvmap',
    function(event, code, region)
    {
 
    }
);
jQuery('#vmap').bind('regionClick.jqvmap',
    function(event, code, region)
    {
 
    }
);

Consider that fact that you can use standard features of jQuery events like event.preventDefault() or returning false from the callback to prevent default behavior of JQVMap (showing label or changing country color on hover). In the following example, when user moves mouse cursor over Canada label won't be shown and color of country won't be changed. At the same label for Russia will have custom text.

jQuery('#vmap').vectorMap(
{
    onLabelShow: function(event, label, code)
    {
        if (code == 'ca')
        {
            event.preventDefault();
        }
        else if (code == 'ru')
        {
            label.text('Bears, vodka, balalaika');
        }
    },
    onRegionOver: function(event, code)
    {
        if (code == 'ca')
        {
            event.preventDefault();
        }
    },
});

Data Visualization

Here I want to demonstrate how visualization of some geographical-related data can be done using JQVMap. Let's visualize information about GDP in 2010 for every country. At first we need some data. Let it be site of International Monetary Fond. There we can get information in xsl format, which can be converted first to csv and then to json with any scripting language. Now we have file gdp-data.js with such content (globals are evil, I know, but just for the sake of simplification):

var sample_data = {"af":16.63,"al":11.58,"dz":158.97,...};

Then connect it to the page and add some code to make visualization:

var max = 0,
    min = Number.MAX_VALUE,
    cc,
    startColor = [200, 238, 255],
    endColor = [0, 100, 145],
    colors = {},
    hex;
 
//find maximum and minimum values
for (cc in gdpData)
{
    if (parseFloat(gdpData[cc]) > max)
    {
        max = parseFloat(gdpData[cc]);
    }
    if (parseFloat(gdpData[cc]) < min)
    {
        min = parseFloat(gdpData[cc]);
    }
}

//set colors according to values of GDP
for (cc in gdpData)
{
    if (gdpData[cc] > 0)
    {
        colors[cc] = '#';
        for (var i = 0; i<3; i++)
        {
            hex = Math.round(startColor[i] 
                + (endColor[i] 
                - startColor[i])
                * (gdpData[cc] / (max - min))).toString(16);
         
            if (hex.length == 1)
            {
                hex = '0'+hex;
            }
         
            colors[cc] += (hex.length == 1 ? '0' : '') + hex;
        }
    }
}

//initialize JQVMap
jQuery('#vmap').vectorMap(
{
    colors: colors,
    hoverOpacity: 0.7,
    hoverColor: false
});

Custom Maps

The following is the converter instructions directly from jVectorMap that could be used to create your own maps for JQVMap from the data in various GIS formats like Shapefile. The following command could be used to convert USA map from the data available at www.naturalearthdata.com:

python \
  path/to/converter.py \
  path/to/geo-data.shp \
  path/to/resulting-map.js \
  --width 900 \
  --country_name_index 4 \
  --where "ISO = 'USA'" \
  --codes_file path/to/codes-en.tsv \
  --insets '[{"codes": ["US-AK"], "width": 200, "left": 10, "top": 370}, {"codes": ["US-HI"], "width": 100, "left": 220, "top": 400}]' \
  --minimal_area 4000000 \
  --buffer_distance -3000 \
  --simplify_tolerance 1000 \
  --longtitude0 10w \
