GraphSharp BalloonTreeLayout pins all vertices in one place

Question

I am working on Graph# and need to use BalloonTreeLayout, but the result is the layout groups all vertices in one place together.

My code is :

<Sample:MyGraphLayout x:Name="layout"
                      LayoutAlgorithmType="BalloonTree"
                      OverlapRemovalAlgorithmType="FSA"
                      Graph="{Binding}"
                      AsyncCompute="true"
                      ShowAllStates="false"
                      HighlightAlgorithmType="Simple">
</Sample:MyGraphLayout>

How to do with Graph# to make to this result?Balloon Tree Layout in a commerical product

Thank you!

I have create a dummy graph sample project and i can share it for you. Following features are implemented: double click on vertex, find vertex by id, sample indicator boxes on vertex, context menu (remove vertex, recursive function - show all joined vertices only), labeled edges. Sorry for my english ;)
