MxGraph Indicator Diagram

Recently I have used mxGraph to draw an indicator diagram to indicate active panel in a wizard. Event though mxGraph has a documentation, I found it difficult while working with this framework.

By default mxCell allows one lable per cell. If you need more than that we can insert labels using insertCell or insertVertex. In this example I needed two lables(One for state and other is for name of the state), so I have used vertex and inserted one more vertex to the parent vertex.
