There is a very simple example in the attached notebook. I would like to replace 1,2,3,4 with w,x,y,z. This is for a large matrix where manual entry of characters would be difficult.
What exactly did you do to get that input and output? The input is not a Graph object, so GraphPlot should not accept it. When I try to run that code it gives an error message.
See also my answer below. The 2 lines of code in test1.nb are running "as is". I'll start looking into an upgrade.
What version of Mathematica are you using? Code in the notebook does not work on 12.1.1. VertexLabeling is not a valid option and GraphPlot expects an AdjacencyMatrix.
188.8.131.52 Rohit, thanks again. The S and C (or CC) matrices are producing nice graphs, so maybe this is peculiar to version 11. See the bottom two plots on structureofthegeneticcode.com. Numbers 1 - 64 need to be replaced with A,C, D ... X,Y.
Code is now attached.
I don't see anything in the V11 documentation for GraphPlot that suggests it would work with a non-square matrix as input. Can you please evaluate the following in test2.nb and re-attach.
