Figure 4
(a) An acyclic chain graph; (b) the corresponding unit-distance graph now equalized (i.e. with edges of equal length); (c) an acyclic chain graph; (d) the corresponding unit-distance graph after embedding, untangling and with edges of equal length. Vertices are labelled as described in Section 4.2.1 and dashed black lines show the repeat units of each chain. |
