问题
So far I have received great helps and answers regarding my previous question on d3.tree code.
I have two more questions and hope someone kindly assist me.
Assume I have the same flare.csv file as the one in my previous question (with small modifications), that is,
A
A.A
A.A.B
A.A.C
A.B
A.B.C
A.C
A.C.D
A.D
A.D.A
A.D.B
A.D.D
A.E
A.E.A
A.E.B
A.F
A.H
How can I modify the code such that all links between A and B (that is A is the parent and B is the child) become yellow, for instance? Note that I don't want any change in cases where B is the parent and A is the child.
My other question which is not of my main interest right now, is if it is possible to change the code such that all outer children appear on the outer circle? In other words and in context of my flare.csv, I want
A.F
A.H
A.A.B
A.A.C
A.B.C
A.C.D
A.D.A
A.D.B
A.D.D
A.E.A
A.E.B
all appear in the same layer. Is it possible?
Thank you so much.
