    Kartograph.js

    Kartograph.js is a JavaScript library that renders SVG maps in web browsers. It is built on top of jQuery and RaphaelJS. Please have a look at the API docs for more details.

    Initializing a new map

    map = $K.map('#map', 600, 400);
    map.loadMap('world.svg', function() {
        map.addLayer('countries', {
            styles: {
                fill: '#ee9900'
            },
            title: function(d) {
                return d.countryName;
            }
        });
    });
    ```
     
    Choropleth maps (aka coloring map polygons based on data):
     
    ```javascript
    pop_density = { 'USA': 123455, 'CAN': 232323, ... };
     
    colorscale = new chroma.ColorScale({
        colors: chroma.brewer.YlOrRd,
        limits: chroma.limits(chroma.analyze(pop_density), 'k-means', 9)
    });
     
    map.getLayer('countries').style('fill', function(data) {
        return colorscale.get(pop_density[data.iso]);
    });
    ```
     
    Adding symbols is easy, too:
     
    ```javascript
    cities = [{ lat: 43, lon: -75, label: 'New York', population: 19465197 }];
     
    map.addSymbols({
        data: cities,
        location: function(d) {
            return [d.lon, d.lat];
        },
        type: Kartograph.Bubble,
        radius: function(d) {
            return Math.sqrt(d.population) * 0.001;
        }
    })
    ```
