I am trying to find the Planar code to the following graph. I was told that Planar codes are created by traversing from the Root in such a way that the line is to your right. You write 1 when you take a step away from the root, and you write 0 when you step towards it.

My point of confusion is what dictacts "towards" and "away" from the root? like I can redraw the LHS of the tree as a straight vertical line, and it would clearly have a code that starts with 1111000. this graph should be indistinguishable from it's origional tree as the nodes are still connected in the same way. Is this the correct method of going about this problem?

Also Please show every step of the solution for a thumbs up.
