I already tried all these methods, but choosing a method is not the
issue. There were two issues: first, how to make Mathematica create a
planar-embedded display of CompleteGraph (and more generally, any planar
graph); and second, what happened to one of the vertices and one of the
edges when I used Method -> "HighDimensionalEmbedding".
I now know an easy solution to the second issue -- see a separate post
as a follow-up to [mg87545]; the first one remains unresolved.
