Kartograph map won't display - kartograph

Question

I can't get Kartograph.js to display my .svg map. Here's what I've done:
I've successfully made a .svg map from a .shp using the most basic json file I could with kartograph.py, according to Kartograph's docs, doing the basic world.json -o world.svg. Here's the json:
{
"layers": [{
"src": "ne_50m_admin_0_countries.shp",
"simplify": 3
}]
}
I've set up a simple http host with python and directed chrome to the host, since I understand you can't do this locally.
I've written the code below. I don't get any errors, so I don't what I've done wrong. Could it be that I haven't put in any layers? I wanted to make as simple an example as possible for my first try.
<div id="map"></div>
<script>
function loadMap() {
var map = kartograph.map('#map');
map.loadMap('world.svg', function() {
});
};
</script>
<script src="jquery-1.11.0.min.js"></script>
<script src="kartograph.js-master/dist/kartograph.js"></script>
<script src="raphael-master/raphael-min.js"></script>`
Thanks guys.

You must add the layer of the svg file.
In this case: map.addLayer('layer_0');
All the code:
$(function() {
var map = kartograph.map('#map',800,600)
map.loadMap('world.svg', function() {
map.addLayer('layer_0');
});
});
To see the name of the layer i open the svg file with Inkspace, and then press Shift+Control+X.
