someone could you give me an example to draw this graph? My difficulty is set lengths in each vertex, I use tkz-graph

Uncompleted example

        \Vertex[x=0, y=0]{v1}
        %Continue ...

I think that there is another way to draw

Errera graph

All suggestions are welcome.

    Did you check the graphdrawing library of TikZ in the manual? – percusse Jun 22 '18 at 0:18

    @percusse I am not sure if the algorithms of the graphdrawing library are able to deal with an Errera graph, but I might be wrong. – user121799 Jun 22 '18 at 0:54
  • Thanks @percusse, I found a presentation and a nice article of Graph Drawing in TikZ by Till Tantau and a poster from Graph Drawing and Network Visualization :) – Oromion Jun 22 '18 at 1:52

Luckily Mathematica has the graph data. Unfortunately, my French is practically nonexistent, so I cannot appreciate the benefits of that package.

        \foreach \X/\Y [count=\Z] in {4/ 13, 4/ 6, -0.2/ 5, 2/ 2.2, -6/ -1, 6/ 2.2, 
    9.5/ 1.6, 2.7/ 5, 4.8/ 7.8, 4/ 10.4, -1.5/ 1.6, 14/ -1, 4/ 3.6, 
    5.3/ 5, 3.2/ 7.8, 4/ 0.3, 8.1/ 5}

  • Ingenious answer, @marmot please could you show how you got that data (if it's in Mathematica commands), I would also like to get your graphs from Solfer, Heawood. I think Mathematica has something similar to doc.sagemath.org/html/en/reference/graphs/sage/graphs/… – Oromion Jun 22 '18 at 3:02
  • @Oromion Here is the link to the Mathematica notebook. I just typed GraphData["ErreraGraph"] // InputForm and used a regex c & p to convert the vertices to the list in \foreach, and the edges I drew by hand because I figured that understanding the Mathematica syntax for that may take longer. – user121799 Jun 22 '18 at 3:10
  • Fantastic, thank you so much, it works :) i.imgur.com/qbMWTCF.png – Oromion Jun 22 '18 at 3:35
