Controller page :
public class treenodes
    /* Wrapper class to contain the nodes and their children */
    public class cNodes
        public List<Contact> parent {get; set;}
        Public Account gparent {get;set;}
        public cNodes(Account  gp, List<Contact> p)
            parent = p;       
            gparent = gp;   
    /* end of Wrapper class */
    Public List<cNodes> hierarchy;
    Public List<cNodes> getmainnodes()
        hierarchy = new List<cNodes>();
        List<Account> tempparent = [Select Id,Name from Account];
        for (Integer i =0; i< tempparent.size() ; i++)
            List<Contact> tempchildren = [Select Id,FirstName,LastName from Contact where AccountId = :tempparent[i].Id];
            hierarchy.add(new cNodes(tempparent[i],tempchildren));
        return hierarchy;

Its showing me all the accounts which are there in my org but it has to show only parent account and its related account hierararchy.
