Need a good UI development tool for newbie for a complex org chart or family chart

I have a very complex org chart or a family chart with con开发者_Go百科fusing relationships. For eg. a child can have multiple parents and each child will have multiple properties which can point to another data up in the tree(like a dotted relationship) The data set is multiple rows of data. I want to represent them in a good UI tool. which one will be easy to learn and host or make it a stand alone application. I tried looking into other questions but doenst satisfy me much.
