The three versions are required to give all the tones of the scale in the middle double, and, as promised, they are in the proper vertical positions. When more than two harmonic directions are involved, they can't all be perpendicular. For consistency, I chose to have all links diagonal up to the right, rather than mix left and right. But it has the advantage that each tone always appears in the same place, regardless of the type of harmony diagrammed. Of course, a harmonic diagram of an overtone scale is rather superfluous, but it makes the point that this method can diagram harmonies involving any prime intervals, in a consistent way.
Many variations are possible.
And a tone not related to any other by a prime harmony could be connected by multiple links, shown dotted. For a more compact diagram, all the horizontal distances could be reduced proportionally. As for actually drawing these diagrams, I used a computer plotter for accuracy and neatness, but graph paper works well too. If one were only interested in relative pitches, the pitch-line would be the clearest picture. Or if one only wanted to see harmonic relationships, then a harmonic network using horizontal, vertical, and maybe some diagonal links would be clearest.
