jQuery Mapael

Overview

jQuery Mapael is a jQuery plugin based on raphael.js that allows you to display dynamic vector maps.

For example, with Mapael, you can display a map of the world with clickable countries. You can build simple dataviz by setting some parameters in order to automatically set a color to each area of your map and generate the legend. Moreover, you can plot cities on a map with their latitude and longitude.

As Raphaël, Mapael supports Firefox 3.0+, Safari 3.0+, Chrome 5.0+, Opera 9.5+ and Internet Explorer 6.0+.

Key features

How to add new maps ?

Maps for the world, France and USA countries are available with Mapael. It's easy to create new maps, so feel free to add new ones. The first step is to retrieve the SVG file of the wanted map. You can find this kind of resources on Natural Earth Data or Wikimedia Commons. Then, you have to create a new JS file from this template :

(function($) {
    $.extend(true, $.fn.mapael, 
        {
            maps :{
                yourMapName : {
                    width : 600,
                    height : 500,
                    getCoords : function (lat, lon) {
                        // Convert latitude,longitude to x,y here
                        return {x : 1, y : 1};
                    }
                    elems : {
                        // List of SVG paths for building the map
                    }
                }
            }
        }
    );
})(jQuery);

You have to set the default width and height of your map. If you want to plot cities, you will have to customize the getCoords() function that takes as arguments a latitude and a longitude, and returns x,y coordinates depending on the map projection (mercator, miller, ...). Then, the last step is to open the SVG image with a text editor and copy the paths definitions into the "elems" parameter. In order to use your new map, you need to load the JS file, and set 'yourMapName' for the Mapael 'name' parameter.
