How to use individual country files

[tanyona]

I'm just getting started with datamaps. Not sure how the individual country files are meant to be used e.g.

<script type="text/javascript" src="${pageContext.request.contextPath}/js/datamaps-0.5.8/datamaps.ken.js"></script>

var map = new Datamap({
    element: document.getElementById('container')
});

I get an error in the browser console - data.objects is undefined
