Figure 9
A planar finite unit-distance graph in which the 1–5 and 4–5 edges (shown in red) are (a) shorter and (b) longer than the other edges; (c) the unit-distance graph in (a) and (b) now equalized; this unit-distance graph is forced into a non-planar arrangement by equalizing the 1–5 and 4–5 edges; (d) a planar unit-distance graph in which the 1–3 and 2–3 edges are shorter than the 1–1, 1–2 and 2–2 edges; (e) the unit-distance graph in (d) now equalized; it is forced into a non-planar arrangement by equalizing the 1–3 and 2–3 edges. Vertices are labelled as described in Section 4.2.1

and dashed black lines show the repeat units of each chain.
