javascript - Displaying bubbles in Kartograph.js -


i trying create bubbles on svg map generated kartograph. want this: http://kartograph.org/showcase/symbols/

the map loads symbol not display. have no errors thrown in javascript console.

$(document).ready(function() {  var map = $k.map('#map');  map.loadmap("mapfinal.svg", function() {     // add layers     map.addlayer('background', {         styles: {             fill: '#e8f9fb',             'stroke': 'none'         }     });     map.addlayer('world', {         styles: {             fill: '#f5f3f2',             'stroke': 'none'         }     });     map.addlayer('states', {         styles: {             fill: '#fff',             'stroke': '#882222',             'stroke-width': 0.5,             'stroke-opacity': 0.4         }     });     map.addlayer('urban', {         styles: {             fill: '#553344',             'fill-opacity': 0.6,             'stroke': 'none'         }     });     map.addsymbols({         type: kartograph.bubble,         data: [{             lon: -104,             lat: 40.5,             name: 'berlin'         }],         radius: 40,         location: function(d) {             return [d.lon, d.lat]         },         style: 'fill:#800000; stroke: #fff; fill-opacity: 0.5',     });  });

});

i don't know else do. have followed example code , read docs.

in case else runs in future, issue map itself. whatever reason, there bug in kartograph.py framework generates sqg maps incorrect coordinates. bubbles not showing because longitude , latitude not present on map. when regenerated map using laea projection, worked.
