Branches dendrogram or correlation flows

I would like to do a hierarchical chart using dendrogram or correlation flow.
Here is an example of data and output
Src Dst Value
A B 0.5
B C 0.3
D E 0.5
I have used option source and data from the same base value but still do not form the hierarchical chart.
Network chart can do but looks more confused.

Please advise.
Thank you very much.
