This doesn't solve all of the problems but helps with some of them.
Adjust the ImageSize and AspectRatio for the space available.

Manipulate[
 GraphPlot[
  Table[i -> Mod[3 i + 1, n], {i, n}],
  VertexRenderingFunction ->
   ({White, Disk[#1, .1],
      Black, Text[#2, #1]} &),
  DirectedEdges -> True,
  Method -> "HighDimensionalEmbedding",
  PackingMethod -> "ClosestPacking",
  AspectRatio -> GoldenRatio],
 {n, 10, 200, 1, Appearance -> "Labeled"}]
