2 Visualising orbital graphs

2.1 Visualing an orbital graph via the DOT format

2.1-1 DotOrbitalGraph

Returns: A string

Warning: This function requires version 1.4.0 of the Digraphs package, or newer.

Given an orbital graph D, this function returns a string that contains a description of D in DOT format.

The edge of D corresponding to its BasePair (1.3-1) is coloured red, while the remaining edges are coloured black.

The DOT string for D can then be compiled and displayed with the Splash (Digraphs: Splash) function of the Digraphs package.

See https://en.wikipedia.org/wiki/DOT_(graph_description_language) for more information about this format.
