Display Account and its related Contacts in lightning:tree view

I just came to know about lightning:tree tag which is a cool tag to represent the role hierarchy.

Am trying to display Account and its related contacts in this lightning:tree structure. Through some examples from salesforce, I can able view tree structure with some hard coded value but it'll be helpful if I can load the dynamic Account and its related Contacts in this lightning:tree view.

Ex from salesforce:
    <aura:handler name="init" value="{!this}" action="{!c.doInit}" />
    <aura:attribute name="items" type="Object"/>
    <lightning:tree items="{! v.items }" header="Roles"/>
    doInit: function (cmp, event, helper) {
    var items = [{
            "label": "Western Sales Director",
            "name": "1",
            "expanded": true,
            "items": [{
                "label": "Western Sales Manager",
                "name": "2",
                "expanded": true,
                "items" :[{
                    "label": "CA Sales Rep",
                    "name": "3",
                    "expanded": true,
                    "items" : []
                    "label": "OR Sales Rep",
                    "name": "4",
                    "expanded": true,
                    "items" : []
        cmp.set('v.items', items);

I think you need to frame the record set as a JSON object in the server side controller and pass it to the client side. In the client side map the JSON recordeset to the 'v.items'
