Hello,
I have hierarchy variable:
Europe
Africa
Asia
Europe#England
Europe#England#London
Europe#England#Manchester
Europe#England#Liverpool
Africa#Egypt
Africa#Egypt#Cairo
Asia#China
I want to create a pie chart that contains the first child (for ex. England - 4, Egypt - 2 and China - 1)
something like this:

How can i do that?
Thank you!
