Are A1 and A2 different each time you call f or are they constant?

comment Implementing a LineStyleFunction for line plots
@J.M. I was trying to show how to be a bit more general than just positive or negative.

comment Argmax in a List
Good stuff. That's what I enjoy about this site and about Mathematica. You're likely to get a readable solution, a fast solution, an alternative solution, an obscure solution, a silly solution, and a comparison between them. They all add to one's knowledge.

comment Drawing dessins d'enfants (bipartite graphs subject to certain conditions)
And the white nodes (of degree 3) can be simplified. For a face with $2k$ edges, you can replace $k$ white nodes with a single node of degree $k$. Then make a planar embedding of what's left with the appropriate vertex degrees. Then replace the special nodes with their associated face. The replacement might get a little tricky if faces share edges. But your {18,2,1,1,1,1} is essentially a tree.

comment Drawing dessins d'enfants (bipartite graphs subject to certain conditions)
Omitting the black nodes is more than just for clarity in the case they are all of degree 2. They're not really relevant for laying out the graph. Once you've laid out your white nodes, the black ones just go in the middle of each edge. Or hang off the side for your two edge faces.
