This is an incremental post to navigating your family tree from a few months back. This builds off of that visualization technique to manipulate the tree into a radial view. Also, as with the original, the tree is 100% dynamic and you can reset each node in the tree as the root node, toggle between tree views as well as change the API you are analyzing.

Within this post I will walk through building the ancestor tree (a binary tree), feel free to reach out if you want more information on how the descendant tree was built, but will leave that to the imagination for now.
First things first, the credits. I started this effort with two main inputs, (1) the node tree link diagram that was explained and created by Jeffery Shaffer and (2) thedynamic parameter posts that Nelson Davis recently went through. I rely on both of these to get to the family tree viz shown here. In addition to these, I also askedAllan Walker, Noah Salvaterra and Anya A’Hearn for general help and guidance along the way.
