SharePoint 2013 organisation browser empty in non-mysites

To fix the issues please refer to http://spreza.blogspot.ch/2013/03/using-sharepoint-2013-organization.html
You need to place the script under Organisational browser webpart on the same page.
<script type="text/javascript"> function CreateHierarchyChartControl(parentId, profileId, type, persistControlId) { var i = profileId.indexOf("|"); var claimsmode = profileId.substr(i-1,1); if((i >=0 ) & (claimsmode=="w")) { profileId = profileId.substr(i+1,profileId.length-i-1); var initParam = profileId + ',' + type + ',' + persistControlId; var host = document.getElementById(parentId); host.setAttribute('width', '100%'); host.setAttribute('height', '100%'); Silverlight.createObject('/_layouts/ClientBin/hierarchychart.xap', host, 'ProfileBrowserSilverlightControl', { top: '30', width: '100%', height: '100%', version: '2.0', isWindowless: 'true', enableHtmlAccess: 'true' }, { onLoad: OnHierarchyChartLoaded }, initParam, null); } } </script>

However, the script is better to be placed in embeded HTML, rather than in Content Webpart.
