Build/view/Edit hierarchy into an Org Chart

I can't give you a solution (you could try the Marketplace), however some C# I wrote recently to traverse the employee tree using the employee `ManagerId` which may be of use as a starting point (it returns a list of all staff subordinate to the starting employee):

using Terrasoft.Configuration;
using Terrasoft.Core;
using Terrasoft.Core.DB;

using System;
using System.Data;
using System.Collections.Generic;

namespace Terrasoft.Configuration.UsrEmployeeTree
{
	public class EmployeeTree
	{
		private UserConnection UserConnection;
		private Guid employeeId;
		
		public EmployeeTree(UserConnection userConnection) {
			UserConnection = userConnection;
		}
		
		public void TraverseTree(Guid employeeId, List<Guid> staff) {
			staff.Add(employeeId);

			var select = new Select(UserConnection)
					.Column("Id")
				.From("Employee")
				.Where("ManagerId").IsEqual(Column.Parameter(employeeId))
					as Select;

			using (DBExecutor dbExecutor = UserConnection.EnsureDBConnection()) {
				using (IDataReader dataReader = select.ExecuteReader(dbExecutor)) {
					while (dataReader.Read()) {
						TraverseTree(dataReader.GetGuid(dataReader.GetOrdinal("Id")), staff);
					}
					dataReader.Close();
				}
				dbExecutor.Close();
			}
		}
	}
}

impressive, will try it out
